Focus Groups and Usability Testing in Redesigning an Academic Library's Web Site

ABSTRACT

As the World Wide Web has advanced since its inception, librarians have endeavored to keep pace with this progress in the design of their library Web pages. User recommendations collected from focus groups and usability testing have indicated that the University of Scranton's Weinberg Memorial Library's Web site was not working as intended, and the library's home page, in particular, was cluttered. Focus groups indicated that the process of accessing the library's databases from off-campus took too many steps, key resources were not located in key areas of the page, links were too close together, and the font was too small. Library staff determined it was necessary to rethink and redesign its pages. Self-reports from focus groups were insufficient to get at the mechanics of Web page use. Through usability testing, librarians were able to observe students and faculty completing simple research and directional tasks. Before “going live” with the new page in January 2007, users who had participated in the focus groups and in the usability testing were surveyed about the redesigned library Web page. The users indicated that the new Web page was less confusing, easier to use, and somewhat more intuitive than the previous library Web page. Web sites are always works in progress, and academic librarians should be proactive about making changes to their library Web sites to take advantage of emerging technology and to meet user expectations.

Overhyped Fad or Missed Opportunity? A History of Academic Libraries and the Social Web

The emergence of social media has radically transformed the way we create and consume information. These changes have in turn given rise to new models of librarianship centered on principles of participation, interaction, and collaboration. Over the last decade, academic libraries have eagerly adopted social media as a means of enhancing services and connecting with a new generation of users. But how exactly has this technology changed libraries? In what ways has the social web transformed library services or our relationships with users? This article attempts to assess the impact of social media on academic libraries in the United States through a review of the literature published since 2005. In particular, it looks at how academic libraries have used social media to improve or develop new services. By comparing published case studies with the theoretical literature, this article seeks to separate theory from practice and determine the extent to which the social web has transformed library practice. The author concludes that, despite several noteworthy examples, the majority of social library applications ultimately fail to live up to the transformative potential promised within the literature and that this failure may have more to do with philosophical rather than technical limitations.     

Website usage metrics: A re-assessment of session data

Metrics derived from user visits or sessions provide a means of evaluating Websites and an important insight into online information seeking behaviour, the most important of them being the duration of sessions and the number of pages viewed in a session, a possible busyness indicator. However, the identification of session (termed often ‘sessionization’) is fraught with difficulty in that there is no way of determining from a transactional log file that a user has ended their session. No one logs out. Instead a session delimiter has to be applied and this is typically done on the basis of a standard period of inactivity. To date researchers have discussed the issue of a time out delimiter in terms of a single value and if a page view time exceeds the cut-off value the session is deemed to have ended. This approach assumes that page view time is a single distribution and that the cut-off value is one point on that distribution. The authors however argue that page time distribution is composed of a number of quite separate view time distributions because of the marked differences in view times between pages (abstract, contents page, full text). This implies that a number of timeout delimiters should be applied. Employing data from a study of the OhioLINK digital journal library, the authors demonstrate how the setting of a time out delimiter impacts on the estimate of page view time and the number of estimated session. Furthermore, they also show how a number of timeout delimiters might apply and they argue that this gives a better and more robust estimate of the number of sessions, session time and page view time compared to an application of a single timeout delimiter.
