Subject: Weeding guidelines

I would like to know what age criteria other libraries have set in their 
weeding guidelines for particular parts of the collection. For example, 
how many years old may a science book be? A computer technology book? I 
would like to know any and all date restrictions others use for each part 
of the collection. Thanks

Hi

This is a meld from a couple of libraries in New Zealand and Australia - for public libraries.

5.1 Thanks to Joseph Segal in his book Evaluating and weeding collections...ALA, 1980,there is an easily remembered acronym for factors which detract from a books usefulness.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

M - Misleading (and /or inaccurate)

U - Ugly (worn and beyond repair)

- Superseded (by a new edition or a better book on the subject)

T - Trivial (poor literary or scientific merit)

Y - Your collection has no need for this book (irrelevant to the current or future customer)

6.3 Audio Visual

Where a part of a multiple-item audio-visual title is missing or damaged, do the following:

·change status to “AV-INCOMPLETE”

·Test items reported faulty before discarding. Customers often report items as faulty due to faults with their player

·Consider that audiovisual items are often difficult to borrow on Inter-Library Loan

·Taped Book cassettes can be replaced unless the pack is too old. For instructions on how to order replacement tapes, refer to the document “Replacement of Audio Visual Materials”


DISCARD

MEND/REQUEST REPLACEMENT TAPES
Videos with a use count of 200 

Videos of very low use count

Taped Books or Cassettes that are less than 12 months old
Taped Books and cassettes with a use count of at least 25 that are in very poor condition
Taped Books or Cassettes that are more than 12 months old but still in good condition
Any material that cannot be mended or replaced

6.4 Magazines


How long to keep for
Frequency of publishing
6 months
Weeklies
2 years
Monthlies
Up to 5 years
Less frequently produced titles

6.5 Reference Collection

·The use of printed reference materials can be difficult to determine as they usually do not circulate and we do not keep an in-house use count.

·Generally use the criteria used for the lending collection, with the possible exception of use and currency.

·Some are considered reference ‘classics’ while others, especially medical, legal, scientific and technological works may become outdated very quickly. These need close assessment before being sent to another branch or transferred to the lending collection.

·Many of our reference sources are on Standing Order. These are updated annually or as new editions are published. The outdated editions need close assessment before being sent to another branch or transferred to the lending collection. An exception is any new edition that supplements rather than replaces an older edition, such as quotations books, Australian Dictionary of Biography, etc.

ABS

·The  Australian Bureau of Statistics (ABS) collections reflect the content of the Library Extension Program (LEP).

·The LEP does not include all publications produced by the ABS. We are subject to the retention guidelines for LEP libraries. These guidelines are not hard and fast rules and need to be considered in conjunction with local needs. However, the ABS Website does list the branches that have LEP collections and therefore we should weed to their guidelines whenever possible.

·Additional information about what to keep in your LEP collection is available on the ABS website at: http://www.abs.gov.au
