Weeding is a thorough and conscientious effort to achieve a well-balanced collection suitable to the patrons served, and should be a continuous, consistent process. Hence, books and materials which are out of date or do not meet the stated objectives of the Library and/or are in poor physical condition will be systematically removed from the collection.

Replacement of material being withdrawn or items damaged or missing is not necessarily automatic. The need for replacement is based on:

1. Number of duplicate copies
2. Existence of adequate coverage of the subject in the collection
3. Demand
4. Availability of more current and/or better quality material
