As academic librarians prepare for accreditation reviews and visits, more librarians find themselves having to prove that their library collections are sufficient for the educational programs offered at their institutions. So, how do librarians demonstrate to external accreditors and senior-level administrators that their library collections are sufficient for their educational programs? A team consisting of the Director of Libraries, the Director of Institutional Effectiveness and Research, Academic Deans and Department Heads, and faculty members came together to conduct a self-assessment of the various library collections and compare the collections to the content being covered in specific educational programs. The presenters of this presentation were part of this team and will provide participants with resources and tools for conducting peer analysis for library collections according to expectations set by external accreditors, such as regional accrediting agencies and program accrediting agencies. These resources will provide data for librarians to use as evidence of the quality of library collections and their alignment with educational programs. The results from these analyses can also be used as part of budget requests and help further the development of a collection. Best of all, most librarians are already submitting data to external surveys that are part of the tools and resources discussed in this presentation.
