contents	Accessibility Trends among Academic Library and Library School Web Sites in the USA and Canada Schmetzke, Axel Comeaux, David Foreign Countries North Americans Library Schools Web Sites Followup Studies Academic Libraries Accessibility (for Disabled) Information Science Education Compliance (Legal) This paper focuses on the accessibility of North American library and library school Web sites for all users, including those with disabilities. Web accessibility data collected in 2006 are compared to those of 2000 and 2002. The findings of this follow-up study continue to give cause for concern: Despite improvements since 2002, library and library school Web sites still tend to contain many barriers. A low correlation between the 2002 and 2006 data point to much up-and-down movement in Web accessibility. Contrary to findings derived from the early data sets, the comparison of the 2002 and 2006 data shows that redesign had a positive impact on accessibility. The paper concludes with the warning that advocates of accessible Web sites cannot yet relax: despite the overall positive trend, with so much up-and-down movement in Web accessibility occurring, today's leaders may turn into tomorrow's laggards--unless special vigilance and efforts keep this from happening. (Contains 1 table, 2 figures, and 4 notes.)
