The University of Michigan Library wanted to learn more about the kinds of searches its users were conducting through the "one search" search box on the Library Web site. Library staff conducted two investigations. A preliminary investigation in 2011 involved the manual review of the 100 most frequently occurring queries conducted through the site search box over the course of a month. Those 100 search terms accounted for 16 percent of total queries and were largely one-word searches for databases. In the follow-up investigation, the Library embarked on a more ambitious exploration of the 454,443 searches conducted during the winter 2011 semester, devising a method for selecting, categorizing, and summarizing user search queries. A sample of 1,201 searches from the search query logs was examined; after eliminating duplicate searches, there were 992 unique terms available for categorization. Using a non-overlapping sample of queries, a rubric was developed for categorizing user searches. Each of seven library staff members reviewed all unique terms in the sample to categorize them into the best fitting category from the rubric. After establishing a threshold for reliability among the individuals categorizing the queries, 862 unique search terms were analyzed. Based on this analysis, the most frequent kinds of searches conducted in the winter semester in 2011 on the University of Michigan Library's Web site were specific databases (28 percent), topical/exploratory types of queries (28 percent), and books (including searches by title, ISBN, call number, or a combination thereof) (16 percent).Within the sample, known-item searches comprised nearly half (44 percent) of searches in the sample. Another fifth (20 percent) of total searches were categorized as "exploratory," supporting the need to provide broader, subject-based paths to information through the site. Somewhat surprisingly, there were a small number of article searches (article titles, or mixed searches of journal names and authors and/or title words) in the search box-an indication that users understand the University of Michigan Library primary search box is not for articles.

PurposeThe aim of this case study is to present one library's experiences consulting with a usability expert during the design and implementation phases of a new academic library website and the lessons learned during the process.Design/methodology/approachThe library staff worked with the consultant so that he understood the work of the librarians and goals for the website. Together the consultant and library staff developed a series of tests to measure the usability of the site. The librarians implemented the tests, gradually taking the leadership role in the process.FindingsThe study confirms the value of usability testing as a tool to bring to light some of the ambiguities and complexities of a library website for users. The study demonstrates that librarians have developed an expertise and knowledge base that transfers well to the evaluation of websites and online resources. The experience of the University of Michigan AAE Library reveals that usability testing should be an ongoing exercise so that the website remains relevant to the users.Practical implicationsThis study advises librarians of the value of testing and that, on the one hand, test results confirm what one imagines about the users' experiences, but on the other hand they reveal the unexpected strategies and understandings of the users.Originality/valueThis case study provides a useful example of the value of working with a usability expert, a discussion of what to expect during the process, and advice about the role of the librarian in such an endeavor.

Libraries are increasingly embracing user experience (UX) and user-centered design principles to improve the satisfaction and success of library users. Electronic resources management can utilize such principles to better support users as they interact with the library"s website and its employ to improve the user experience. These strategies include utilizing basic UX principles when designing sites and interfaces; analyzing quantitative data to inform the library on how such sites are being used; recruiting strategies for library user studies; and, finally, a call to move to a more unified user experience and to work more closely with vendors on improvements to help users succeed.
