A Book That You Wrote

Due to the high cost of evaluating, processing and cataloging donated materials, the library does not add donated items to the circulating collection. We may acquire self-published books when they include unique local content, fit the scope of the Library’s collection plan and meet our selection criteria, including quality, accuracy, and editing.
