Library Users Expect Link Resolvers to Provide Full Text While Librarians Expect Accurate Results

A review of: Wakimoto, Jina Choi, David S. Walker, and Katherine S. Dabbour. "The Myths and Realities of SFX in Academic Libraries." The Journal of Academic Librarianship 32.2 (Mar. 2006): 127-36. Objective – To determine how successful the link resolver, SFX, is in meeting the expectations of library users and librarians. Design – Analysis of an online user survey, library staff focus groups, retrospective analysis of system statistics, and test searches. Setting – Two California State University campus libraries in the United States: Northbridge, with over 31,000 students on campus, and San Marcos, with over 7,300 students on campus. Subjects – A total of 453 online survey responses were submitted from library users, 421 from Northbridge and 32 from San Marcos. Twenty librarians took part in the focus groups conducted with library staff consisting of 14 of the 23 librarians from Northbridge (2 from technical services and 12 from public services), and 6 of the 10 San Marcos librarians (3 from technical services and 3 from public services). No further information was provided on the characteristics of the subjects. Methods – An online survey was offered to users of the two campus libraries for a two-week period in May 2004. The survey consisted of 8 questions, 7 fixed response and 1 free text. Survey distribution was enabled via a different mechanism at each campus. The Northbridge library offered the survey to users via a pop-up window each time the SFX service was clicked on, while the San Marcos library presented the survey as a link from the library’s home page. Survey responses from both campuses were combined and analysed together. Focus groups were conducted with librarians from each campus library on April 20th, 21st, and 29th, 2004. Librarians attended focus groups only with others from their own campus. Statistics were gathered from each campus’ local SFX system for the 3-month period from September 14, 2004, to December 14, 2004. Statistics from each campus were combined for analysis. The authors also conducted 224 test searches over the 3-month period from July to September, 2004. Main results – Analysis of the surveys revealed that 80% of users expected to see a full-text article online when they clicked on the SFX button; 20% expected to rarely or never see one. Responses also gave an almost equal split when users were asked if the SFX service met their expectations with 49.5% saying it did and 50.5% saying it did not. The free text survey question asking for comments on the user’s overall opinion of SFX received 174 responses, 26% of which were positive, 40% negative, and 34% mixed. The primary theme expressed in 49% of all comments received was disappointment in not gaining full-text access. Thirty-three percent of other comments were classed as having a general theme, while the remaining 19% of comments regarding the SFX service were categorised with themes of complexity, technical problems, efficiency, or confusion. Results from the librarian focus groups differed between the two campuses. Northbridge librarians had 50% to 85% confidence in the accuracy of SFX and were generally impressed with the service. San Marcos librarians had 60% to 100% confidence that SFX would work, however it was also discovered that several participants had suspicions regarding the accuracy of the system. The SFX usage statistics obtained covered 188,944 individual uses of SFX at both campuses. Statistics showed that 48% of these uses resulted in the user clicking on an option provided, either linking to full-text, catalogue look-up, or inter-library loan form access. Of total occurrences, 39.7% had a link to full-text displayed; this link was accessed 65.2% of the time. Forty-seven percent of SFX uses provided a catalogue link (23.8% of which were accessed) and 37.9% of uses provided an inter-library loan link (8.4% of which were accessed). The test searches revealed anomalies to take into account when analysing the SFX usage statistics, including that about 15% of SFX requests display multiple full-text links. Of the test searches conducted, 22.2% of full-text availability results ended in either technical or accuracy errors and 8.8% of catalogue look-ups produced errors. In those cases where errors did not result there were also significant percentages of instances where the library did not have access to the desired resource: 35.3% of searches correctly indicated that no full text was available, and 57.6% correctly linked to the catalogue to show that the periodical was not held locally. While these are correctly generated system results they are still likely to be seen as unfavourable outcomes by users. Conclusion – The results of the study indicated that both library users’ and librarians’ expectations of SFX were slightly higher than their actual experiences. Librarians’ primary concerns related to the need for more accurate results while library users wanted more full text. It was noted that many complaints associated with SFX were likely to actually be problems with systems that SFX links into rather than the software itself. Although imperfect, SFX, and link resolvers in general, are noted to be a vast improvement on the many separate searches required in the past to locate full text and undoubtedly user expectations and demand for 100% seamless accessibility will grow.
