AbstractAbstract Purpose - The purpose of this paper is to present longitudinal data on the accessibility of 56 North American academic library web sites, as well as insights into the connection between accessibility and certain design methods and technologies. Design/methodology/approach - Bobby 3.1.1 was used to evaluate compliance with the Web Content Accessibility Guidelines 1.0. Also studied were the main method of page layout (CSS versus HTML tables), whether a content management system was used, and whether skip-navigation links were employed. Findings - The percentage of Bobby-approved pages has remained consistent around 60 percent in 2010 and 2012. However, the percentage of errors per page, a metric more sensitive to the pervasiveness of accessibility barriers, has steadily and significantly decreased. Sites whose layouts are built with cascading style sheets have fewer errors per page than those that use tables for layout. Sites that use a CMS have considerably higher percentages of approved pages and fewer errors per page than sites that are not built with a CMS. Research limitations/implications - The principal tool used, Bobby 3.1.1, is capable of detecting only a subset of accessible design principles. Future studies should examine compliance with the newer WCAG 2.0 guidelines. Practical implications - The use of a content management system may have a positive impact on accessibility. While this study reveals some promising trends, more education and continued advocacy is needed to increase web accessibility at libraries. Originality/value - This is the only study that provides up-to-date trend information about the accessibility of a broader set of academic library web sites (a set not limited to one state) over an extended time period. It is also the only accessibility study comparing academic library web sites that use a content management system to those that do not.
NotesThis paper presented longitudinal data on web accessibility of 56 North American (both Canadian and the U.S.) academic library web sites. The results showed Canadian library web pages (n=7) were more accessible than the US sites (n=49) in 2012, in terms of the percentages of pages approved and the average errors per page. For the average approved pages, there was a drastic increase from 2002 to 2006 whereas the number remained steady after 2006. However, the average number of errors per page decreased steadily since 2002. Interestingly, whereas in 2002 the Canadian academic library web sites were less accessible than North Amerian sites in general, they have gradually taken the lead in terms of both accessibility metrics. The tendency for the accessibility leaders to remain leaders was also becoming stronger year after year. There's also a strong relation between table-based sites and the high numbers of errors per page, compared to the CSS-based sites. Using a content management system (CMS) was also identified as having a high correlation with the high accessibility with regards to the two metrics.
