I partnered with the Yakima Valley Libraries (YVL) in order to assess and evaluate their Spanish-language collection and how they select for that collection. Around the United States and Canada, there has been a trend of low number of library materials in Spanish even when the community in which the public library serves has a significant Spanish speaking population. There are many interwoven factors as to why this occurs including funding and community interest. YVL has made extraordinary strides in improving their general collection development and want to continue to improve their Spanish-language materials and services. My project provides an evaluation of how well their existing Spanish-language materials are circulating and suggestions on how to improve the collection in order to better serve their Spanish speaking community.
