Abstract

The University Library at the University of Illinois at Urbana-Champaign (UIUC) Services Advisory Committee has established a program to create a regular rotation of patron surveys. The program is an effort to answer basic questions about attitudes towards the library's services, facilities and collections. Modeled directly after those surveys designed and carried out at the University of Washington Libraries, the UIUC plan calls for an annual rotation of three surveys, each focused on a different user group. The first group surveyed (spring 2004) consisted of graduate and professional students, to be followed by undergraduate students (spring 2005) and faculty (spring 2006). Surveys will be conducted annually thereafter so that each user group will be surveyed every three years. Results from the first UIUC web survey, with 1400 respondents, revealed that graduate and professional students are very satisfied with their library experiences and the pattern of responses by subject discipline corresponds with the findings of Hiller (2002) at the University of Washington, but with some predicted shifts. "How-tos" for the web survey are discussed and included, along with a link to two sets of data analyses. In addition, lessons learned from the survey experience are discussed and suggestions are made for the presentation of data to successfully communicate survey results to decision makers.

Introduction

After long admiring the longitudinal patron survey program established at the University of Washington Libraries (Hiller 2001, 2002), the Services Advisory Committee at the University of Illinois at Urbana-Champaign initiated a similar program in fall 2004. The purpose of the program is to establish communication with our patrons, offering them a simple way to provide feedback and ultimately to both influence decisions and provide direction concerning the library's services, facilities and collections.

Graduate and professional students at UIUC number about 10,000 and account for approximately 41% of all library book circulation, by far the group with the highest checkout-per-person rate (Kruger 2001). UIUC's decentralized library structure was established over 100 years ago to bring library service into the departments. This is a research library model that includes service to the upper division undergraduate student, but which is primarily geared to graduate students and faculty. Because of the heavy use of library materials and services in this user group, graduate and professional students were selected to be the first group surveyed. A "survey of the whole," rather than a sampling method was selected. The survey was considered easier to conduct via the web since all graduate and professional students could be contacted with a single email distribution and it allowed us to easily market the survey to a single group. It is acknowledged that web-based surveys often result in lower response rates than printed/mailed surveys (Kwak & Radler 2002). Because of this possibility, an examination of respondents and their representation of the graduate and professional student population at UIUC was conducted as part of this study.

The UIUC library has conducted a number of other user surveys over the past few years, including UIUC Library-conducted web surveys in 1998, 1999 and 2000 (Schmidt & Searing 1998, 1999, 2001) and LibQUAL+ surveys in 2001 and 2002. The earlier surveys, conducted 1998-2000, were anecdotal in nature and open to anyone on campus. LibQUAL+ results, while interesting, were not locally focused enough to provide specific answers about individual departmental libraries. Although the LibQUAL+ data showed high satisfaction levels with UIUC libraries, it is important to better define how users perceive the library and to collect their opinions about library priorities for the future. The new survey is designed to collect data related to the primary and secondary library used by the survey respondents in order to provide specific feedback to these units.

Previous Research

User surveys are widely-used tools reported often in library literature as summarized by Hiller (2001, 2002). SPEC Kit 280 (Diamond 2004) reports the results of a survey of ARL member libraries on the use of library user surveys. The survey found that library user surveys varied widely by process type, scope, and method of execution, and the use of web-based surveys is increasing.

Hiller and Self (2002) described and compared a separate series of library user surveys administered at the University of Virginia and the University of Washington (UW). They concluded that user surveys are valuable tools, while acknowledging their limitations, and stated that user survey results are most useful when combined with other data. Hiller (2001) compared University of Washington Libraries' surveys with results from UW participants in the ARL-sponsored SERVQUAL (LibQual+) pilot. Hiller concluded that both LibQual+ and locally administered surveys have value, however local institutional issues are probably more effectively addressed by locally administered surveys.

Hiller (2002) used the UW survey data to compare library use, priorities, and information needs by academic discipline. Comparisons were made by broad academic area (Health Sciences, Humanities-Social Sciences, Science-Engineering, and Other), faculty vs. graduate students, and year of survey (1998 & 2001). Survey results revealed significant differences between academic disciplines. Areas of similarity were also noted, as well as changing use patterns and priorities. Hiller (2004) used the 2001 survey data to compare how geoscientists and scientists in other fields (Chemistry, Mathematics, Physics, Psychology, Zoology, and Engineering) find information and use libraries. He concluded that, in 2001, the UW earth science faculty were more dependent on print resources than other scientists, but predicted that, due to the addition of many online resources in the earth sciences, the trend would be toward increased use of electronic resources and decreased physical visits to the library.

Recent research conducted by the University of California Libraries (Schottlaender et al. 2004) measured the use of print journals placed in storage that were also available electronically. This study also reported results of a User Preference Survey conducted among faculty, graduate and undergraduate students, staff and health professionals by broad academic discipline, and concluded that electronic journals are "popular, extensively used, and pervasive", although to a lesser extent for arts and humanities and for undergraduate students. However, print format remains important. Problems with electronic journals include unavailability of some older issues, and also some recent issues, omission of some types of content, usability and printing barriers, and access problems.

Survey Expectations

Based on the long-standing perception that academic disciplines use library materials differently and also on the results previously reported at the University of Washington showing the research differences between academic fields (Hiller 2002), the authors expected UIUC survey results to mirror these findings and show that differences in research material use and library use continue to be different between, for example, the sciences and the humanities. It was expected that humanities disciplines would report more reliance on print-based materials and therefore higher in-library use, while science disciplines would report a higher use of online resources and remote library use.

Despite the fact that differences were expected in how the disciplines use research material, the authors also believed the data would begin to show a blurring of these lines as more research material in every discipline becomes available online and Internet use becomes a more widely-used part of every discipline's research model. The widespread use of Internet search engines may be influencing this generation of library users.

UIUC Methodology

The surveys previously conducted at the University of Washington (UW) (http://www.lib.washington.edu/assessment/) provided the UIUC Library Services Advisory Committee with a series of sample surveys on which to base the questionnaire. A subcommittee was formed to draft a survey; very early in this process the decision was made to conduct a purely electronic, web-based survey. With the UW's consent, it was also decided to replicate some of the University of Washington Libraries' questions in order to compare the results from the two institutions because UIUC and the UW libraries serve similar groups of users.

Because human subjects were involved, the Research Board at the University of Illinois required an application form and permission to conduct the survey. Email notification to each graduate or professional student on the UIUC campus was determined to be the best way to solicit participation. After submitting our application and agreeing to the required security and privacy regulations, approval to survey this group of 10,172 individuals was granted by the UIUC Research Board. A graduate research assistant was then hired to program the web survey and database to collect the responses.

Pre-testing the Survey

After completion of the first draft, the web survey was pre-tested with a group of graduate student assistants working in the UIUC Grainger Engineering Library. This group was selected for the pre-test due to their library experience as students in the Graduate School of Library and Information Science and because they met regularly as a group for reference meetings. This group was expected to be more critical than the larger population since they had library backgrounds and felt comfortable with the survey authors who administer other science library units. They were asked to make comments about the survey in focus group sessions following their completion of the survey. The first "live" test session resulted in numerous changes. Pre-testing determined the length of the survey was perceived to be overly long, although it only took about 15 minutes on average to complete. In addition, the group disliked some of the questions that asked them to determine multiple facets for an answer, such as importance and satisfaction. After making changes based on the pre-test, the group was asked to take the survey a second time a week later. Only a few small changes followed the second pre-test, resulting in a survey that took an average of ten minutes to complete because questions from the first iteration of the survey were both simplified and eliminated in order to streamline the survey.

Comments from the pre-tests were very helpful in creating a web-based survey. Pre-test participants noted that they felt that a huge difference exists between a paper survey and a web survey. Many felt a web survey was inappropriate for questions that took long, thoughtful answers or that asked for complex relationships to be explained (for example, satisfaction and importance). A web survey, from the perspective of the pre-testing group, needs to be succinct, clearly formatted, and timed to be completed in less than ten minutes. These characteristics are not unlike those outlined in a Rand publication discovered after most of our web survey was completed, but which has been very helpful in documenting mistakes to avoid in the next survey (Schonlau et al. 2001).

Survey Costs

Total cost of the survey, not including librarian time, was $1,750.00. Approximately 100 hours of graduate research assistant work went into programming, database creation, and analysis for a total of $1,300.00. An additional cost was the campus email distribution charge of $50.00 and gift certificates to the Illini Union Bookstore which were awarded as incentives for participation. A total of $400.00 was budgeted for incentives, two $100 gift certificates and four $50.00 gift certificates. Participants were encouraged to enter a drawing for the certificates as a thank-you for taking the survey. It is anticipated that future surveys will not be as expensive since the initial web survey has been created and will only be modified as changes are needed, although campus fees for mass email distribution to undergraduate student are higher ($150.00 per mass mailing) due to the larger size of the population surveyed, and a second email reminder may be sent during future surveys.

Approximately six librarians contributed hours to the survey, five who served on the Library's Services Advisory Committee and one supervising computer/web work. Librarian hours spent on the survey were estimated to total no more than 20-30 hours. Because we relied heavily on previous work done at the University of Washington Libraries, it was felt that there was no need to hire a consultant or to conduct further background work. Our motto became "just do it!"

Confidentiality and Security

Like most research institutions, the University of Illinois is concerned with providing security and protecting the confidentiality of its students. Before gaining the permission of the UIUC Research Board to implement the survey, the Library agreed to take deliberate steps to secure our web site and to remove any links created between a student's survey responses and their identity. In addition, a separate database was set up to receive the email addresses of any respondent who wished to be considered for the prize drawing, again to separate them from survey responses. Bluestem, a method for providing reliable client identification for database applications, already in place on UIUC servers, was used to validate users to take the survey. It also provided a level of security by admitting authorized users only. Once entered into the survey's host server, users were able to re-enter if they failed to complete the survey in a single session. This feature proved very useful when the first day's onslaught of respondents brought down our initial server site. If so moved, users could return at another time to complete the survey. Once finished, the survey did not allow them to enter the site again.

Initial Problems

A few problems arose during the first few hours of the survey. The email invitation to participate in the survey was distributed late Sunday evening by automated campus delivery. Early Monday morning as students read the notice, they literally stopped the survey by crashing the server when 800 persons attempted to logon at the same time. We obviously underestimated the number of concurrent respondents and this database failure resulted in some turn-aways. On the survey's second day it was switched to a more robust SQL server. No further problems were encountered, but this lesson is well-learned since our next survey will include the undergraduate population at UIUC which is estimated at about 26,000 students. It will be critical to either stagger the email announcements about the survey or to test the database and server for hundreds of simultaneous users before launching the survey.

One surprising result of this server crash was the number of respondents who took the time to tell us they could not complete the survey. Email addresses of library personnel to contact with questions or problems were included throughout the survey. Many emails were received explaining their problems with the survey and a willingness to continue the survey when computer problems were solved. A few individuals, mostly computer science majors, even offered opinions on what went wrong with our design and how they would fix it. For the most part, very thoughtful comments were received and demonstrated the goodwill the library has among this constituency.

Presentation of Results

The successful presentation of survey results is as important as the data collection itself. Since the survey data were collected to inform decision makers, it was essential to provide the data in an extremely accessible and approachable format. At UIUC, the departmental library structure allows for decision making at many levels, including at the local departmental library level. Since the data were collected, at minimum, to inform unit managers about impressions and opinions concerning their libraries, the data needed to be easily manipulated and viewed. This objective was achieved by programming a web site hosting survey analysis data.

The web site (see http://g118.grainger.uiuc.edu/gradsurvey) is organized numerically by survey question. Within each question a number of choices can appear, allowing for different analyses. For example, Question 4, "Which University libraries do you use on a regular basis?" allows viewers to choose the department reported and sort the results by frequency (primary or secondary library used). It is part of the flavor of the survey to know that while most Chemistry Department graduate students use the Chemistry Library most frequently and the Biology library second-most frequently, other libraries are also selected, including the Undergraduate, Physics, and Grainger Engineering libraries. Like most questions, Question 4 can be "filtered" by any of the campus departments. With each of the thirteen questions offering this type of manipulation, the results are enticing and interactive rather than flatly presented in what would be a massive spreadsheet.

Some attrition took place during the survey. Each question analysis reports the number of survey respondents for that question. This attrition can be attributable to either the first day's system failure, where respondents did not return to finish the survey, or to general drop-off due to busy schedules or disinterest in the survey.

A popular feature of the results web site is the respondents' comment text boxes. All comments can be viewed by the library used most frequently or second-most frequently, but with some viewing experience it is clear that respondents use many libraries and their comments were not always focused on a single library. Reading text box comments from the survey is like eating jelly beans - you just can't stop once you start. The comments are real and often pointed ("Chemistry library does a good job of getting me the materials I need to do my research. However, it could use a facelift. It is very unpleasant to study there and I have gotten splinters from some of the tables"), but just as often laudatory about the importance of libraries ("UIUC would be nothing without its library.").

While conducting analyses for this paper, the data were grouped by division. "Sub-question" results were created, and these too have been made readily available to all web site viewers (see http://g118.grainger.uiuc.edu/gradsurvey/division). Questions marked "second analysis" are those which needed further tweaking in order to compare to UW data. It is possible to continue to mine the data in order to tease out needed responses. The results are both many-layered and as simple or complex as desired. The primary goal was to provide data to fit the needs of many viewers in order to facilitate use of the data. A secondary goal was to be sure the data presentation was neither unwieldy nor overly complex so as to discourage use.

Results and Discussion

Survey Respondents

1,400 responses were received during the two weeks the survey was advertised and the web link was open. An announcement about the survey and an invitation to participate was sent from University Librarian Paula Kaufman via email to 10,172 graduate and professional students on the UIUC campus. While 1400 respondents represents only a 14% response rate, this number is larger than the total population responding to University of Washington Libraries' most recent surveys (which were print surveys mailed to sample groups, not web-based, whole population surveys) which found 563 graduate students responding in 2001 (a 40.4% sample return rate) and 457 graduate student responding in 1998 (a 45.7% sample return rate) (Hiller 2002). There are approximately 10,000 graduate and professional students at the University of Washington (Hiller 2002). In hindsight, a longer survey period with more aggressive marketing might have collected a higher response rate at UIUC. For a first-time effort, 1400 replies provide a good baseline from which to build.

A literature review by Kwak and Radler (2002) indicates that the response rates of electronic surveys have been lower than for traditional mail surveys, "with the advantage of mail survey over email or web surveys ranging from 8% to 37.2%" The response rates for the first wave of their comparison study were 24.2% for the mailed survey and 18.1% for the web survey. Schonlau et al. (2001) discuss response rates for web and mail surveys. In Chapter 3, their overview noted that "response rates range from 7 to 44 percent for Web surveys and from 6 to 68 percent for e-mail surveys. " (Schonlau, p. 20). In addition, direct comparison studies between postal mail surveys and email surveys show that, "in most studies, the mail response rate was higher by as much at 21 percent." (Schonlau, p. 21). Libraries conducting web-based or email surveys might expect to have lower response rates than traditional, postal mail surveys, although the number of respondents might be higher than a postal mail, sample survey.

Figure 1 shows the respondents' primary department and degree program by broad discipline. At the UIUC libraries, departmental libraries number over 40 and are primarily geared to subject disciplines. The departmental libraries are grouped by "division" and this library structure was used to determine how respondents' departments would be categorized. For example, persons replying that their primary department was related to chemistry, math, engineering, physics or geology are considered to belong to the physical sciences or engineering category at UIUC, since these libraries comprise the Physical Sciences and Engineering Division. Because the number of respondents from Area Studies was low in number, this division could not be statistically considered in the divisional analysis. These departmental affiliations were moved into the Social Sciences Division for the divisional analysis. Full disclosure showing which departments were included in each division or broad discipline is found at http://g118.grainger.uiuc.edu/gradsurvey/division/DEPARTMENTS.doc The UIUC Library also has a Central Public Services Division, a Special Collections Division and a Technical Services Division, which were not included in this analysis because they do not have a subject focus.

Because it was important to determine how those responding to the survey by discipline corresponded to the total populations of these areas, Figure 2 was created to show the departmental distribution of graduate and professional students at UIUC for fiscal year 2004 by division. These departmental enrollment numbers were grouped by division using the same criteria as for Figure 1. The respondents are shown to be reasonably representative of their populations.

Figure 2. Distribution of graduate and professional students at UIUC 2003-2004 by library division.
[figure 2] While the data are able to provide representative results by broad (divisional) discipline, there were often not enough respondents choosing a specific primary departmental library to make a reliable analysis of the data at that level. Even anecdotal opinions and written comments about departmental libraries have proved interesting and worthwhile.

Five of the thirteen questions allowed respondents to provide written comments, and those five questions generated 1336 replies. A few participants emailed complaints about the survey, unhappy that the web comment boxes limited responses to 255 characters; some respondents had much more to tell us. With many more written comments than we expected, these short text messages about library services and collections are fascinating to read. In general, comments are positive and provide a window on graduate students' perspectives of the library. All comments can be read online, grouped by question (Questions 4, 9, 10, 11 and 13), at http://g118.grainger.uiuc.edu/gradsurvey/division/.

The Findings

Overall, graduate and professional students are highly satisfied with UIUC library services and collections, as shown in Table 1. Satisfaction with library services is highest among Physical Sciences and Engineering graduate students while Arts and Humanities have a slightly higher satisfaction with library collections than other disciplines. It is also important to note that nearly all respondents were library users. Question 2 asked, "Have you used the University Library's services or collections (either in-person or remotely) during this academic year?" Only 2.4% of respondents answered no, with 97.6% answering positively. While it may be self-selective since this was advertised as a library survey, clearly library use is important among graduate and professional students.

*Note: Although 1400 persons started the survey, by question 13, shown in Table 1, only 1278 persons responded. Attrition was evident throughout the survey and the results web pages reflect the loss of participants with each successive question.

Table 2 shows type of library use by discipline conducted at least weekly in UIUC libraries by graduate and professional students. Science graduate students (both life, physical and engineering) visit the libraries least often in person as a percentage by broad subject discipline, but report higher use of libraries through office computers, most likely due to having access to online serials, their primary source of research material. Arts and Humanities graduate students report using libraries in person at a higher percentage than other disciplines, demonstrating their continuing need for access to print materials or other library services, including library computers and study space. Humanists also report having the highest percentage of library use from home computers. It may be that they are the group least likely to have an office computer available to them. Most users are reporting more frequent use of the library remotely rather than in person on a weekly or more frequent basis.

*Note: Although 1400 persons started the survey, by question 3b, shown in Table 2, only 1382 persons responded. Attrition was evident throughout the survey and the web pages reflect the loss of participants with each successive question.

The data in Table 3 show what graduate students report they do while visiting the libraries in person. The question reported in Table 3 is, "Why do you visit the University libraries in person? Mark how often you do the activities listed below in the primary library you use." A marked difference in both types of materials used and frequency of use is demonstrated in this table. For example, 58.3% of Arts and Humanities students report looking for books in the library at least weekly, while only 24.7% of Physical Science and Engineering students perform this activity at this rate. These data reflect the nearly classic depiction of the disciplines that says humanists read books and scientists read articles. Today this might be restated that humanists read books in print and scientists read articles online. While stereotypical, this assumption garners some support from the data in Table 3: in terms of percentages, scientists look for books at least weekly in the library at less than half the rate of humanists. Numbers of users (rather than percentages) is another useful way to view the data. Because there are more science graduate students on the UIUC campus, this group does visit libraries to look for books in larger numbers than humanists.

The most-often reported reason for visiting libraries in person in three of the four broad disciplines is "individual study/work." This is the second-most reason given among humanists, who reported "look for a book (print)" as their top in-library activity. These data support the "libraries as place" phenomenon and demonstrate the continued need for libraries as meeting, study, and discussion places, a separate identity from the need for library collections and services.

*Note: Although 1400 persons started the survey, by question 6, shown in Table 3, only 1339 persons responded. Attrition was evident throughout the survey and the web pages reflect the loss of participants with each successive question.

When asked to identify library activities done remotely, Table 4 shows respondents reported 2.97 uses per person in this question compared to 2.28 uses per person for the "in-house use" questions (Table 3 total responses = 3065, respondents =1339; Table 4 total responses = 3927, respondents = 1320), even though there were more selections possible for in-house use. This possibly indicates a greater amount of remote use in general. Of Arts and Humanities graduate students, 58.1% reported using electronic article indexes at least weekly, very close to the 61.9% of Physical Science and Engineering graduate students who reported using electronically available indexes at least weekly. This can be attributed to the comparable number of online databases now available in these fields and the fact that, due to low use and budget constraints, many print indexes have been cancelled in recent years - online may now be the only way to use many subject-specific indexes. Use of online journals remains higher in the sciences, most likely due to the larger number of journals in that format available to science graduate students.

It is important to note that nearly 70% of total graduate and professional students report they search the UIUC online catalog at least weekly (Table 4), while only approximately 32% report they look for a print book in the library at least weekly (Table 3). Our "front door" for this constituency is the Library Gateway (http://www.library.uiuc.edu/) or unit web pages, not physical libraries. This is critical information when designing any type of service or choosing collections to support this group of users. It will be interesting to see if, in upcoming surveys, undergraduates and faculty also report greater online use of libraries compared to on-site visits.

It was also expected that survey results would show that differences in how different disciplines rank the importance of research material types (books, print journals or electronic journals) would be less pronounced in 2004 than those previously reported by Hiller (2002). The authors planned to compare the UW's 2004 survey data to UIUC's 2004 data. Both surveys were to cover graduate and professional students only, and would include a question concerning the perceived importance of print journals, electronic journals, and books. At UIUC, question 9 asked, "Please indicate the importance of the information resources listed below, based on the primary library you use." Since the populations of the two institutions are considered to be similar, the 2004 responses to this question were expected to be similar. A problem arose when attempting the comparison since the UW survey did not repeat this specific question in 2004. Although this lack of comparable data prohibits definitive conclusions, the comparisons created in Table 5 are nevertheless noteworthy. In Table 5, a row showing the percent range of difference between the disciplines' ranking was calculated for each year and material type. The data show a decrease over time in the differences between the disciplines from 1998 to 2004, indicating more agreement about the importance of these material types.

For example, in 1998 27.5% of UW graduate students in the humanities and social sciences ranked electronic journals "very important," while 52.3% of health sciences students and 47.3% of physical science and engineering students agreed with this ranking. The range between these agreements varied from 10.6% (between the Life & Health Sciences and Science/Engineering Sciences) to 90.2% (between Life & Health Sciences and Humanities/Social Sciences). In 2001, the range of differences grew smaller (7% - 56%), meaning their views on this ranking became more alike and less divergent. In 2004, at UIUC, the gap is the smallest, in a range of 5.3% -20.4%.

The data from Table 5 are graphically displayed in Figure 3 and show some interesting trends. Most obvious are the parallel trends in the perceived importance of print journals (trending downward) and electronic journals (trending upwards). Apparently the different disciplines are becoming more alike in their perception of the importance of print and electronic journals and are trending in the same directions.

Although the range of difference apparently is shrinking, and is smallest at UIUC in 2004, the percentage of graduate students at UIUC ranking books as "very important" is higher than at UW. This could be due to something as simple as the definition of "books" on each campus, which could include not only monographs, but book series, dissertations, and conference proceedings, or the relative size of the monograph collections at each institution. Even though the adage links books and humanists together and scientists with journals, in fact at UIUC in 2004 these disciplines have very similar opinions concerning the importance of books as research materials. Further research is needed in order to determine why books are ranked higher at UIUC compared to the UW.

Data showing the importance of different material types from the UW Libraries' surveys of 1998 and 2001 (Hiller (2002), Table 7) shown with data from the 2004 UIUC study (http://g118.grainger.uiuc.edu/gradsurvey/division/analyze_q9b.asp). Percentages are based on those respondents from each subject area selecting print journals, electronic journals or books as "very important" for their research (selecting 5 on a scale where 1 is "not important" and 5 is "very important.").

It is not surprising that life and health science fields rank the importance of print journals slightly above other disciplines, possibly due to the color plates and detailed diagrams this field depends on. Science and engineering graduate students at UIUC in 2004 show the lowest percentage of users who consider print journals to be "very important." This is most likely due to the fact that the sciences have access to more electronic journals than non-science fields, and because electronic journal backfiles have been produced and made available first in science fields, greatly reducing the need for print journals. Another scenario is the possibility that this group of researchers may be ignoring relevant literature when it is not available online. This trend has been noted recently by Blowers and Williams (2004) whose research shows that "online journals show rapidly increasing citation rates while journals available only in print are leveling off."

Although not conclusive due to the use of data from two different institutions, the data in Table 5 indicate that the disciplines are becoming more alike in their opinions concerning the importance of books, print journals and electronic journals.

Library Priorities from the Survey

One of the primary reasons to conduct the survey was to generate a sense of user expectations. A "priorities" question was designed, asking, "Please select the items you think the University Library should have as priorities during the next three years." A list of 19 services or collection-related items was given to choose from, and respondents could choose as many priorities as they wanted. A comment box was included as optional. Attempts to design this question with rankings or "what not to do" choices were eliminated during the pre-test, considered to be too negative and cumbersome. In addition, restrictions, such as choosing five top priorities, were also discarded as too limiting. The results for this question, shown in Table 6, speak volumes about how our users wish us to proceed. With a nearly unified voice UIUC graduate students from every discipline wish for more electronic resources. The single small departure from this theme is the humanists' top priority, "Maintain the quality of University Library print collections," an option that garnered only three more votes than their second priority (and everyone else's first priority), "Provide electronic access to current articles." When ranked by total votes as shown in Table 6, the top five priorities all relate to increasing electronic access, including shifting resources from print to electronic.

The priorities question also resulted in 151 comments (select "View Comments" at http://g118.grainger.uiuc.edu/gradsurvey/division/analyze_q11.asp to view these in their entirety). Our clientele provided us with substantial reading and much food for thought. Although the respondent's primary and secondary libraries are listed with their written comments, it is interesting to note that most graduate and professional students use numerous libraries and comment on many of them, not only on the primary library they use.

Tips (or, What We Learned)

A great deal was gained from the survey and much was learned, both about the survey itself and about library users. Although other libraries will learn more by conducting their own surveys, some important points surfaced that might help along the way or persuade libraries to try a web-based user survey.

Conclusions

While tables and figures graphically show us which libraries are used most frequently or what's on the minds of graduate and professional students, there are other ramifications to this survey. Data from this UIUC survey combined with previous research at the University of Washington (Hiller 2002) indicate that, although some differences remain between disciplines in terms of how libraries are used and what type of research material is needed, the gap is closing. Stereotypes are changing and with them library models for research.

In order to keep pace with these changes, it is critical to continue to ask users what they do in libraries, how they use library materials, and their perceptions about their library needs in the future. It is even more critical for libraries to respond and make changes based on those findings. The UIUC survey results do demonstrate that an appreciation of libraries is shared among our graduate student constituents, who have very positive feelings concerning library collections and services. It also appears that, although there was a small constituency calling for a continued focus on print collections, which our libraries have no intention of abandoning, the overwhelming majority of users have demonstrated a substantial interest in electronic resources. In order to maintain the excellent relationship we have with this clientele, we must be willing to change with them and continue to support their needs.

The challenge to libraries is how to move our collections from print to electronic to meet the needs of our users. These changes involve not just a format change, but modifications to budgeting, cataloging and access, staffing, facilities, equipment - nearly every aspect of what we do everyday. Change is hard and cultural change is very hard, but having survey results that so clearly point the way is a great step in confirming that, by taking these steps, we are on the right path.
