As mentioned in a class email, Carol A. Singer has an article about weeding in the recent issue (Volume 47 Issue Number 3, Pages 256 -264) of Reference & User Services Quarterly.  This issue is available on the shelf at the GRC, or is available online. Here is the abstract:

 A major review of the reference collection in Bowling Green State University’s Jerome Library was made necessary by the decision to incorporate the materials from the reference collection in the science library. The process of planning and implementing this collection review is described, emphasizing how this process has been affected by changes in technology and the demands made by library users. Suggestions that may help ensure a successful review are included.
