To make weeding as painless as possible, a series of reports has been created to help you weed your collection. These reports are available on Web Reporter, located under the weeding folder then OCLC/CREW. Many of the reports in this folder are designed to run on just one Dewey Call number and to work cooperatively with the CREW Manual. A resource designed for School Libraries, Less is more a practical guide to weeding school library collections, also recommends utilizing and adjusting the CREW manual to help weed school collections. There are also other general reports that look at items that have not circulated in the last 10 years, material that may be older than 10 or 20 years, and fiction materials that have not circulated in 5 years.

Remember that the reports are here to help you make judgement about what to weed and what to keep and are not simply a list of items to discard. Use the CREW Manual Dewey ranges below or the Dewey ranges listed in Less is more a practical guide to weeding school library collections to help make discard decisions.

Shelf List

If you want to begin analyzing your collection one small section at a time a good reporter to use is Generic Item List in the Collections and Weeding section of Web Reporter.

You can also use Item Reporter out of Horizon to accomplish similar goals, but larger collections will cause problems will Horizon’s performance and so Web Reporter is recommended.

No Circ in 10 years This report is a good place to begin weeding. It will look at all your items that have have not circulated since Aug 1st 2003, about the time SELCO migrated to Horizon. The item must have been created before this date in order to appear.

Older than 10 years

This report looks for items with a publication date and a created date prior to 2003. These items have been in the system for at least 10 years and may be older than 10 years. Since SELCO’s policy is to keep multiple bindings/reprints/versions on one Bib record some of the items on this report may appear to have older publication dates then the actual item in hand.
Older than 20 years This report looks for items with a publication date and a created date prior to 1993. These items have been in the system for at least 20 years and may be older than 20 years. Since SELCO’s policy is to keep multiple bindings/reprints/versions on one Bib record some of the items on this report may appear to have older publication dates then the actual item in hand.
Duplicate Copies on a Title This report will give you a list of titles that have more than one item attached. Choose location and collection to narrow down list. This is an excellent report for finding multiple copies of a title, but be careful of multi-part titles like encyclopedias or TV series with disc broken apart.
Collection Age Reports

Collection Age, Based on Publication Date is a report that will tell you the percentage of you collection by collection code that falls into certain date ranges. This is a good report to run to get a general idea of which of your collections may need some attention.

To get the age of of a certain Dewey Range, run the appropriate CREW weeding report by Dewey range below. These reports include publication date of the title. Export your results to Excel and average out your years using excel’s functions. You will need to do some cleanup of the publisher. For help with this contact the Help Desk.

Value of Collection The collection value report shows the average value of items in your collection by collection code.

Another report in Web Reporter, Average value of collection, shows a great deal more information than the collection value report.  This report shows the average item price for a given collection and location.  This report is filtered by location and collection.  It includes collection, collection description, item location, and average item price.
