Balance in the Adult nonfiction collection is determined by use and demand. The library seeks to select materials of varying complexity and format because it serves mainly the sixteen-year-old to adult patron covering a wide range of educational and interest levels. The library strives to develop a collection that considers currency, content, scope, depth of coverage, and popularity. A strong core collection in each Dewey area should be maintained, supplemented with electronic sources which meet the same selection parameters as the print collection.

The collection is continually evaluated in terms of use, currency, content, depth, and popularity. Continuous weeding and responsible replacement of damaged or lost titles helps maintain a collection that reflects changing needs and library goals.
