7. What are the reasons that weeding doesn’t get done?
11. "Librarians have a responsibility for discarding unsound books of yesteryear. In the eyes of the public, the fact that they are on the shelves confers upon them an endorsement.“ --Clarke, G. E. "Propaganda." Library World, 42:62-63, October 1939
13. 80/20 Rule (Pareto Principle) 20% of your books are responsible for 80% of your circulation

34. Tips Weed as you go—when an item is in hand Set small daily or weekly goals Have a contest Form a support group – “Reluctant Weeders” Make a chart of the stacks and color in where you’ve weeded Have your weeding kit ready to go
56. Quick & Dirty Consider weeding: Duplicate copies no longer needed Items in obviously poor condition Drab items that get lost on shelves Older single title authors Obscure or ephemeral titles Knockoffs of popular authors (Series of Unfortunate Events, Harry Potter) Lesser works of authors who have died Minor author/poet collections Series books when titles are missing Simplified/abridged classics Jeanette Larson, Small Library Mgt. Training Program, Collection Development Course
57. Steps to Weeding Gather usage statistics Maintain a weeding kit Study the area you will be weeding Weed Double check in indexes & bibliographies Dispose of weeded materials—discard, recycle, sell, donate Order replacements or put on a wish list to reorder when funds are available Merchandise low circulating, high-quality items
59. Advice for Specific Sections: Picture Books Think boutique (high-quality, current selection) Be aware of ephemeral interests Board books should be replaced more often since they get the most abuse Replace worn copies of perennial faves (multiples)
60. Advice for Specific Sections: YA Fiction Be ruthless in this section Currency is key Paperbacks >5 years, remove if not circulating well
61. Advice for Specific Sections: C&YA Non-Fiction Anything is not better than nothing Be aware of online resources Better to lack books that have bad information Use CREW Guidelines by Dewey Class as in adult sections
62. Other C&YA Issues Abridged classics (often poor quality) Series books (often poor quality, replace if titles don’t stand alone and collect for various reading levels) Older titles – beware of dated look, torn pages, shabby bindings Worn classics should be replaced (Don’t be sentimental!) Geography titles older than 5 years – toss Science, medicine, inventions – rapid changes so update every 5 years Textbooks – gauge by demand in community and homeschool population
63. Advice for Specific Sections: Reference Older editions may be weeded when superseded Materials should be periodically evaluated, (not as often as circulating collection and not as continuous) Different replacement schedules (new editions may not be as frequent) Keep websites and databases in mind Consider integrating reference materials into the circulating collection, especially if usage is poor
64. Advice for Specific Sections: Periodicals Current use – use declines drastically 5 years after publication date Interest in circulating older issues – do you allow back issues to circulate? Full-text availability Space
65. Advice for Specific Sections: Media Subjective Criteria Worn out Out-of-date Rarely used Supplied elsewhere Trivial or faddish
66. Keepers Volumes of sets and series with special merit Older reference works augmented by (not superseded by) later editionsi.e. Bartlett’s Familiar Quotations Local history Works by local authors
67. Classics Debate It’s our duty as librarians to expose people to “great” literature. Unless a movie comes out based on a classic, are people still reading them? Read Read
68. Keys to Weeding Success Make weeding part of policy Build weeding into the regular work schedule Inventory as you weed Follow up on questions/problems Consider the collection as a whole

Hinweis der Redaktion
One of the most inspiring ideas in librarianship is S. R. Ranganathan’s Five Laws of Library Science. The third law is”Every book, its reader.” This law, in Ranganathan’s words, "urge[s] that an appropriate reader should be found for every book.” Robert Shaw’s 1938 experiment with library shelving proved that library shelves do not allow all books equal chance to be seen by patrons. The graphs in this slide reveal the difference in circulation caused by differences in exposure to patrons. Books on lower shelves are harder to see and reach than books on upper shelves. Shelves further back in libraries are less likely to be browsed than shelves in the front of the library. Look at the circulation pattern of the shelves in the top graph. I have seen this exact same pattern on each section of a whole range of shelves weeded in Great Bend Public Library. The one exception from this pattern was the section with Danielle Steel books shelved on the lowest shelves. Weeding based on past circulation is a measure of circulation. If you see this pattern when you weed, then about 45% of the books you are weeding from the lowest shelves are being removed because they are shelved on the lower shelves, not because they are unwanted by patrons. At least 24% of the books you are removing from the back shelves is because they are on the back shelves and not because they are unwanted. Weeding books because of their location is unethical. Fortunately, there are two things you can do to correct this injustice. First, your book displays should be stocked with books from the lower shelves and the back of the library. Second, weeded books should be displayed before they are completely removed from the library.
