Weeding Policy

Guidelines for Review

Local history is not weeded, all other materials should be reviewed using the MUSTIE guidelines. Weed materials that are:

M = Misleading (or factually inaccurate)
U = Ugly, (worn and beyond mending)
S = Superseded (by a new edition or a better book on the subject)
T = Trivial (of no discernible literary or scientific merit)
I = Irrelevant to the needs and interests of the community
E = The material may be obtained expeditiously Elsewhere through borrowing from another MCLINC or interlibrary loan

List of Suggested Steps in Weeding Process

Print a list of materials in the section that will be weeded that have not been checked out for 2 years if fiction, use CREW Formula for non-fiction.
Pull the materials from the list. You may use a volunteer if one is available and willing.
Physically examine materials to determine: Condition and Copyright date (non-fiction)
Apply the CREW Chart (Appendix A) to non-fiction materials and the Book Condition Chart (Appendix B) to both non-fiction and fiction materials to determine whether to keep or discard. Consider whether an item is in a series when weeding fiction.
If necessary, consult H.W. Wilson’s catalogs for fiction and non-fiction to see if the book belongs in the core collection.
Keep award-winning materials, but only reorder new, popular materials that have been damaged.
Delete electronic record of material in online catalog.
Volunteers or staff stamp material “discard” and destroy barcode.

Discarded Materials

Delete electronic records for discarded materials before:

Books considered appropriate for sale (good condition fiction and non-fiction) will be given to the Friends of the Library.
Books will be donated to charitable organizations upon their request.
Remaining books will be discarded and recycled at the discretion of the librarians.
