Texas A&M University Galveston
What is weeding? Weeding a library is like weeding a garden; one looks over everything and carefully selects those
things which need to be removed. In a library, weeding is a shelf-by-shelf and book-by-book review and withdrawal of
certain books in a library's collection.
Why are we weeding? At the Williams Library, we need to weed the collection for many reasons. They include the
necessity to keep the collection up-to-date and to keep the information available as accurate as possible. Another
reason is that, as the curriculum of Texas A&M University Galveston evolves, the collection needs to evolve, in order to
adequately support it. Books also wear out and fall apart. At other times, certain materials were added to the collection
that no longer fit our collection development policy. For example, there are the multitudes of duplicate copies of many
books, where a single or a couple of copies is now sufficient for our needs. For these reasons, there are always books
and other materials that need to be removed from our collection.
Who decides what to weed? The librarians are all information professionals, trained and experienced in the science of
collection maintenance. Just like collection development, collection maintenance is also taught in graduate library
programs. The professional librarians on the staff are assigned sections of the collection that most closely match their
areas of expertise, education, and interests. Remember that, in addition to a master's degree in library and information
science, all librarians have at least a bachelor's degree in a subject area other than professional librarianship, and some
have additional graduate degrees and certifications in subject areas as well.
What happens when you weed a collection? When faculty members or the professional library staff select material for
withdrawal, the items will be checked against collection development tools such as Best Books for Academic Libraries.
Any title found in Best Books will be returned to the shelf. If a librarian has a question about the removal of a book, a
faculty member in the appropriate department will be contacted. If the faculty member believes the item selected for
withdrawal should be retained, it will be returned to the shelf. If no feedback is received within two weeks, the items
will be withdrawn from the collection.
How often does weeding occur? We try to weed on an ongoing basis, only scheduling organized weeding when
Why do you sometimes weed during the breaks from classes? A large organized weeding is a dirty and difficult job, as
well as a somewhat noisy one. We sometimes schedule weeding activities during a time when the students are not on
campus so that the professional library staff can all participate with a minimum of disruption to the students and other
What input does the faculty have in the weeding process? Faculty input is critical to the success of maintaining a viable library collection, and their input will be solicited and given
full consideration. Notification will be sent to the appropriate Chair/s and faculty library representatives. They will be
asked to notify the entire faculty in their departments. Interested faculty will be directed to a reviewing area of the
library. The weeded books will be available for review during all hours that the library is open.
What if something important gets weeded? Mistakes do happen on occasion, and what gets weeded is also often a
matter of opinion. Books that meet the criteria for withdrawal may be something that is considered vital to a subject
area by a faculty member. If the book hasn't been removed from the premises, we can reprocess it back into the
collection. If it has, then it is too late to recover it. However, each department is given an annual budget for purchasing
new books and materials by the Library. They can choose to replace weeded materials as they see fit. This is the most
important reason why we welcome faculty members' participation in the weeding process.
What happens to the books that are weeded?
Gift Books – sent to Better World Books (betterworldbooks.com) if possible
Purchased with state funds – offer to transfer to faculty departments if wanted. Unwanted books will be shredded.
Can faculty have the weeded books? Absolutely! Our only stipulation is that they ask first, so that we may make sure
they have been fully processed and withdrawn from the collection.
