PurposeLibrary association policies and guidelines are important to study because they reflect consensus values of the profession. As such, they can shape the association, itself, and set the tone for the values of its individual members in their professional practice. From the titles alone, these documents proclaim themselves to be guides for the development of individual library policy. Additionally, as library and information science (LIS) graduate education programs are accredited by national associations, LIS schools pay attention to association policies and guidelines to help shape professional and continuing education. In these ways, they have a role in shaping professional ideology around a topic. The paper aims to discuss these issues.Design/methodology/approachThe services to persons with disabilities policies from three national-level LIS organizations were analyzed through a thematic analysis.FindingsThe guidelines speak to a shared understanding of disability and accessibility around the themes of library staff, library policies and library resources and services. While not surprising, additional themes around disability context and legislation show a shared understanding of accessibility that is much broader than what the legislation requires.Originality/valueAn analysis of guidelines on services to persons with disabilities from the American Library Association (ALA), Australian Library and Information Association (ALIA) and Canadian Federation of Library Associations (CFLA) is of interest because of the ways these organizations intersect. The ALA and ALIA have reciprocal agreements so that students in LIS education programs are recognized as equivalents. Second, the ALA accredits library education programs in Canada. Given these intersecting relationships, the guidelines-shared notions of accessibility become of high interest.
