Over the past twenty years, libraries have grown their services to their patrons from simply offering books and periodicals to now adding multi-media items such as videos, CDs and DVDs.  Add to this the fact that many libraries provide patrons computers to access the Internet as another source for information. Throughout this growth in material resources offered by libraries there are also growing concerns on the security of the collection assets and maintaining (or improving) service levels to the patrons. Many municipalities and institutions have sought ways to reduce operating budgets to offset the growing capital costs of the multi-media resources and computer hardware. Libraries face growing challenges in managing their assets while maintaining high service levels.
