Weeding guidelines

  • Guidelines look like this: 3/10/MUSTIE.
  • The first number is the year since the book's lastest copyright date. copyright dates are found on the reverse side of the title page.
  • The second number is the most recent number of year's since the book was checked out.
  • So the number in this example, 10/3/MUSTIE, should be interpreted as "Books should be discarded if they are over ten years old or have not been checked out in three years.
  • An "X" instead of a number means that that factor "is not applicable to a specific subject."
  • MUSTIE means books should be discarded if they are Misleading, Ugly, Superseded by newer editions or better books, Trivial, Irrelevent to patron interests, easily obtained Elsewhere through interlibrary loan.

These guidelines are part of The CREW Method developed by the Texas State Library. A more detailed explanation of The CREW Method is at www.tea.state.tx.us/technology/libraries/lib_downloads/weeding1.pdf. The fullest explanation of The CREW Method is in the print book, "The Crew Method: Expanded Guidelines for Collection Evaluation and Weeding for Small and Medium-sized Public Libraries" by Belinda Boon, Texas State Library, 1995.
