  • 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.

    59. 59. Advice for Specific Sections: <br />Picture Books<br />Think boutique (high-quality, current selection)<br />Be aware of ephemeral interests<br />Board books should be replaced more often since they get the most abuse<br />Replace worn copies of perennial faves (multiples)<br />
    60. 60. Advice for Specific Sections: YA Fiction<br />Be ruthless in this section<br />Currency is key<br />Paperbacks<br />>5 years, remove if not circulating well<br />
    61. 61. Advice for Specific Sections: C&YA Non-Fiction<br />Anything is not better than nothing<br /> Be aware of online resources<br /> Better to lack books that have bad information<br /> Use CREW Guidelines by Dewey Class as in adult sections<br />
    62. 62. Other C&YA Issues <br />Abridged classics (often poor quality)<br />Series books (often poor quality, replace if titles don’t stand alone and collect for various reading levels)<br />Older titles – beware of dated look, torn pages, shabby bindings<br />Worn classics should be replaced (Don’t be sentimental!)<br />Geography titles older than 5 years – toss<br />Science, medicine, inventions – rapid changes so update every 5 years<br />Textbooks – gauge by demand in community and homeschool population<br />
    63. 63. Advice for Specific Sections: Reference<br />Older editions may be weeded when superseded<br /> Materials should be periodically evaluated, (not as often as circulating collection and not as continuous)<br /> Different replacement schedules (new editions may not be as frequent)<br /> Keep websites and databases in mind<br /> Consider integrating reference materials into the circulating collection, especially if usage is poor<br />
    64. 64. Advice for Specific Sections: Periodicals<br />Current use – use declines drastically 5 years after publication date<br /> Interest in circulating older issues – do you allow back issues to circulate?<br /> Full-text availability<br /> Space<br />
    65. 65. Advice for Specific Sections: Media<br />Subjective Criteria<br />Worn out<br />Out-of-date<br />Rarely used<br />Supplied elsewhere <br />Trivial or faddish<br />
    66. 66. Keepers<br />Volumes of sets and series with special merit<br />Older reference works augmented by (not superseded by) later editionsi.e. Bartlett’s Familiar Quotations<br />Local history<br />Works by local authors<br />
    67. 67. Classics Debate<br />It’s our duty as librarians to expose people to “great” literature.<br />Unless a movie comes out based on a classic, are people still reading them?<br />Read<br />Read<br />
    68. 68. Keys to Weeding Success<br />Make weeding part of policy<br />Build weeding into the regular work schedule<br />Inventory as you weed<br />Follow up on questions/problems<br />Consider the collection as a whole<br />
