Purpose -The purpose of this paper is to evaluate the overall quality of the Louisville Free Public Library's gay, lesbian, bisexual, and transgender collection. Design/methodology/approach -The study implements an inductive check-list method. Where other check-lists compare a list to the collection, ignoring the number of items which do not appear on the list, an inductive method takes a sample of the entire collection, and compares it with several evaluative lists, demonstrating what percentage of the collection is not considered "desirable" by common evaluative lists. Findings -The results found that 31.9 percent of the LFPL's GLBT collection can be found in the evaluative lists used. Previous inductive evaluations suggest that this number indicates a quality core GLBT collection. Research limitations/implications -A sample collection was chosen using GLBT-related subject headings; however, evidence shows that a portion of the actual GLBT collection (perhaps as much as 37.5 percent) lack appropriate subject access control. This results in a potentially flawed sample. Practical implications -This study provides public librarians with a standard by which they can evaluate their GLBT collections and their library's attempt to meet the needs of a frequently underrepresented minority. Originality/value -Very few inductive evaluations have been published, and almost none has been published studying GLBT collections. The paper attempts to fill that gap, and provide a deeper standard by which GLBT collections can be evaluated.
