While the Library will, when necessary, attempt to replace particular missing or damaged items, it does not automatically replace such material. Consideration is given both to the current value of the item to the collection, as determined by application of the selection criteria specified above, and to the records and other evidence of demand for the item. Replacement will often be obviated by the existence of more current material that renders the item obsolete, by shifts in projects and programs at the Institute, and by emerging strengths in other libraries. Wherever possible, missing issues of current volumes of periodicals will be replaced. Back files will be replaced only if there is known demand, and consideration will be given to replacing them with microform.
All replacements are contingent upon funds being available.
