  This survey analyzed the quality of the PDF documents on online repositories
in Switzerland, examining their accessibility for people with visual
impairments. Two minimal accessibility features were analyzed: the PDFs had to
have tags and a hierarchical heading structure. The survey also included
interviews with the managers or heads of multiple Swiss universities'
repositories to assess the general opinion and knowledge of PDF accessibility.
An analysis of interviewee responses indicates an overall lack of awareness of
PDF accessibility, and showed that online repositories currently have no
concrete plans to address the issue. This paper concludes by presenting a set
of recommendations for online repositories to improve the accessibility of
their PDF documents.
