The King County Library System genealogical collections have never been evaluated for their efficacy. This project surveyed the state of the genealogical collections through cataloging of collection material, interviewing the target audience and peers, and analyzing how it serves the community. While there was a range of practices from peer libraries, the target audience showed satisfaction with the current state of the KCLS collections and their accessibility, and current practices were evaluated to be effective with the available labor. With the gathered information, KCLS is better equipped to understand patron needs for this particular collection.
