Selection:
The Libraries can become aware of potentially relevant publications in several ways:
Deselection:
Materials can be considered for deselection when damaged or deteriorated beyond repair (with an option to buy replacements if needed). Monographs with no history of circulation over a significant number of years can be withdraw (through MSU Surplus); works with a history of use but no evidence of imminent use can be transferred to Remote Storage for paged access; little-used works that are rarely held in the BTAA or other U.S. libraries should be retained as part of the "national collection" and can be housed in Remote Storage.
