Discarding of Library materials is necessary to maintain a useful, well kept collection. The purpose of weeding is to reevaluate the collection and to select new or replacement material.
Any material taking up space that could be more profitably used for other materials is subject to reevaluation and discard.
Among those attributes considered will be physical conditions, number of copies available, use, adequate coverage in the field and availability of similar material.
Criteria for weeding
Selection of materials for discarding is based on the following:
· Materials which are no longer timely
· Materials, which have had little recent use and are of questionable value.
· Excess copies of a title no longer in demand.
