Collection Maintenance Continuous maintenance of the collection is carried out based upon systematic evaluation of the collection in light of curriculum shifts, use statistics, core bibliographies, physical space limitations and alternative availability of information. Periodical titles will be reviewed annually prior to their renewal cycle. All other areas of the collection should be reviewed every three to five years. A. Weeding Duplicates Only Weeded At least one copy in good condition of standard and classic titles listed in major general bibliographies and special subject lists should be retained in the collection. In general, emergency management materials should be reviewed every three to five years to remove materials no longer relevant to the curriculum, older materials where sufficient coverage is provided by more contemporary titles, and multiple copies of materials where high use is no longer a factor.
Anatomical texts retain their value longer than other subject areas.
Duplication of coverage should be monitored annually. If the library has a run of less than ten years and the materials covered are indexed by another resource, the volumes should be deaccessioned. Scholarly Journals Long runs of key scholarly journals that meet the criteria given in the introduction to this section should be retained indefinitely. Priority for retention is given to titles accessible through indexing and abstracting services available at Wallace Library and titles not available in any other Rochester-area library. Those including articles of more lasting value are kept longer, especially if they are included in indexing and abstracting services at Wallace Library.
