Open Educational Resources (OERs) are often praised for being more accessible than standard textbooks. In this context, accessibility often refers to low or no costs, or to how students can obtain the resource just by clicking a link. But accessibility also has another meaning: can disabled people access the resource? And in this sense, OERs are no better than the competition. According to UDL on Campus, a 2011 survey of OER textbooks found that nearly half the web-based textbooks (42%) had significant accessibility problems. And of the PDF textbooks, none were accessible to disabled users. This is a tremendous concern.
