are exempt from weeding. We also exclude materials less than two years
All other materials are removed based on usage and percentage of the
All of the collections are grouped into broad categories. Circulation

Collection. In this manner, certain categories do not overwhelm the
collections merely through attrition or popularity. Balance is
maintained. Collection Balance is an aspect of Collection Maintenance
where those percentages are examined for appropriateness on a regular
