Criteria Used When Considering Items to Withdraw

>> Return to Weeding, Deaccessioning, Withdraw

Through the local Millennium library catalog, the NExpress catalog, and OCLC, we can collect significant data to help us maintain a library collection that supports the teaching, learning, research, and intellectual enrichment of our faculty and students. When withdrawing materials (also known as weeding or deaccessioning), the following criteria are often used:

  • Circulation. Our current catalog retains circulation records dating to 1995. Prior to that, we have roughly twenty years of circulation data from our earlier catalog system. Because many books are used without being checked out of the library, circulation data isn't the only criteria we use but it is one objective measurement of the historic use of our collection.
  • Length of time in our collection. While a book may not have circulated at all during its first five years in the library, it's likely not been in the collection long enough to be proved useful. Books held less then five years need more time to prove their mettle and waiting ten years is also a reasonable cut-off.
  • Duplicate copies and earlier editions.
  • Physical condition.
  • Format. One of LIS's responsibilities is too monitor the ever changing media landscape. LP's, eight track tapes, audio cassettes, laser discs, VHS and Betamax tapes form a long list of media types found in our collection at one point or another. Our special collections and college archives serves as a repository for historically important and unique recordings, but recordings used in the classroom are best replaced with a digital copy.

  • Copies held at libraries in the NExpress group and OCLC holding libraries. Books held by two or more NExpress partners or by 30 or more libraries in the U.S. will be easy to order via ILL.
  • Librarian review.
  • Special Collections & Archives review. Middlebury's Special Collections & Archives will review the list for rare materials to be transferred to Special Collections.
  • Faculty review.
  • Guidelines from [Collection Development & Library Policies].
