Collection Development

Challenged Resources

This page contains guidelines and resources for campuses to use when presented with a challenge to a district-purchased resource. These documents help the campus take appropriate steps to acknowledge the individual, check the entire resource, and make sure all parties are heard.

De-selection of Materials

The de-selection of materials (weeding) is as important for collection development as selection. A smaller collection of attractive, relevant, and up-to-date materials is more valuable to students and staff than a larger collection containing outdated or damaged items. The number of items counted as a library’s holdings should represent useful resources. De-selection is a challenging professional responsibility. Community members also often misunderstand it. These guidelines include information intended to support the efforts of those involved in de-selection in both accomplishing the task and in justifying this professional activity.

De-selection should not be attempted during your first year at a site. At schools where there is no certified library staff, the classified staff should request assistance from the Digital Media Literacies Coordinator and District Cataloger.

CREW (Continuous Review, Evaluation, and Weeding)

For more than 30 years, the CREW Method from the Texas State Library and Archives Commission has provided guidance to librarians and staff in libraries about how to cull outdated and no longer useful materials from their collections.

Things to consider when evaluating items using the CREW method include:

  1. Age of the material in the book (copyright date)
  2. Number of times of circulated, date of last use
  3. Presence of “MUSTIE” factors:
    1. M - Misleading and/or factually inaccurate
    2. U - Ugly (worn and beyond mending or rebinding)
    3. S - Superseded by a new edition or better version
    4. T - Trivial (of no discernible literary or scientific merit)
    5. I - Irrelevant to the needs or interests of the community
    6. E - can be obtained Elsewhere

What you need to know before de-selection

  • interests, attitudes, abilities, reading levels, and learning styles of students
  • current curriculum and possible future direction  
  • programs operating in the schools
  • needs of the staff
  • needs of the community
  • strengths and weaknesses of current collection (balance)
  • the ability of the budget to provide funds to purchase more satisfactory items

What to discard

  • worn or damaged materials
  • duplicates (when none is circulating, reduce to one copy)  
  • materials in which information is not easily accessible (e.g. no index or contents)
  • materials that are outdated, inaccurate
  • materials in which the reading level, interest level, or format is inappropriate
  • materials that are no longer in demand or no longer support the curriculum
  • material that is biased, stereotyped, patronizing, or condescending

What not to discard

  • classics texts and award winners
    • Remember that guidelines are not intended to act as a substitute for professional judgment calls and common sense. For example, a sixty-year-old National Book Award Prize winner that has not circulated in more than ten years is simply taking up valuable space and should be discarded even though the library policy may encourage the retention of books that have won awards.
  • items from standard or core collection bibliographies items that are out of print and still have utility in the collection
  • materials of local or regional interest (e.g. Loveland/Colorado History)
  • materials that are unique in content, format, technique

Specific Guidelines by Dewey call number

Dewey Number Subject Guidelines
000 Generalities Value determined by use. Works about computers are quickly out-of-date.
010 Bibliographies Not too valuable if over 10 years old.
020 Library Science Should deal with current standards and practices
100 Ethics, Psychology, Philosophy Value determined by use and interest in a subject
200 Religion Value determined by use. Try to have a collection containing basic information about different religions.
300 Social Sciences Discard outdated social issues which are not of historical value. Controversial topics should be represented from all sides.
310 Almanacs Seldom useful after two years except for teaching purposes. Generally replaceable by online/digital resources.
320 Political Science Material usually dated after 10 years
360 Economics, Las, Government Usually dated after 10 years. Discard career materials after 10 years. Try to keep current on career preparation.
370 Education Keep historical materials if they will be used.
380 Commerce Weed after 10 years except for historical material.
390 Customs & Folklore Weed according to use. Strong, multicultural collections of folktales are important at the Elementary level. 
400 Language Discard old grammar materials; discard other materials according to use.
500 Pure Science Examine materials over 5 years old except natural history. Discard materials with obsolete information and theories.
600 Technology Most material is dated after 5-10 years. Give special attention to those dealing with drugs, space technology, sec education, radio, television, and medicine. Check for historical information. Look carefully at old sewing and grooming books.
700  Arts and Sports Keep basic works in music and art.
800 Literature Keep basic works.
900 History & Geography Weeding depends on use, demand accuracy of fact, and fairness of interpretation.
921 Biography Unless the person has a permanent place in history, should be discarded as soon as use diminishes. Older biographies of mediocre value should be replaced as better materials are published.
R Reference Use the same criteria as for general nonfiction collection.  Encyclopedias are usually dated after 5 years. Pay close attention to atlases. In many cases, these materials can and should be replaced by online/digital resources.
FIC E Fiction Easy Weed dated titles that have not circulated.  Keep “classics” and replace them as needed.

Discarding Outdated or Damaged Materials

Procedure to discard outdated, damaged, or worn-out library-media print/non-print materials.

  1. Apply approved "weeding" methods to the selection of materials to be discarded. (for example: The material still relevant to the study of the West or other instructional materials of possible historical value should be carefully reviewed.) Materials of true historical value should be examined in conjunction with the Digital Media Literacies Coordinator and District Cataloger.
  2. Withdraw the items selected for discard from Destiny by following the following steps:
    1. Click Catalog > Update Copies 
    2. Check the box next to “Track as weeded” 
    3. Select your Reason and Disposal Method from the drop down menus
    4. Place your computer cursor in the Delete Copy rectangle and scan the barcode of the book you choose to delete from your library collection 
    5. See "Update Copies" in Destiny’s online Help for more information 
  3. Generate a Weeding Log in at the end of the year and file it in your records for a year. You can generate this report in Destiny by following the following steps:
    1. Click Reports > Library Reports > Weeding Log
    2. Set the appropriate parameters then click “Run Report”
    3. See "Generate a Weeding Log" in Destiny’s online Help for more information
  4. To prepare discarded materials for disposal, strike through library barcode(s) with a black permanent marker. Strike through the school name using a permanent marker or remove pages that include school/district information. Use your DISCARD Stamp to stamp each book or write discard using a permanent marker on the title page of the book.
  5. Notify school staff and students of the availability of discarded items.
  6. After staff and students have taken what they want, dispose of all remaining items. If there is a large quantity, you may want to request that they be included with discarded textbooks for the school pick-up and disposal.
    1. The campus library staff need to box up their books. Each box can weigh no more than 50 pounds.
    2. Each box needs a completed discard sheet.

    3. Email Materials & Procurement when the boxes are ready to arrange pick up:
