Collection Maintenance
The library does not automatically replace all lost, damaged or worn out materials. Factors such as duplicate copy availability, existence of adequate subject coverage or similar materials and demand are considered before replacement is decided. The same factors are considered when a decision is necessary regarding binding of paper material, re-binding of worn materials, whether purchased, gift, or government depository acquisitions.
An ongoing program of in- house book and binding repair is regularly practiced in order to help maintain the appearance and utility of the book collection. This program is also intended to eliminate a large volume of professional rebinding. Paperbacks judged to be heavily used are purchased with some form of prebinding or cover/spine reinforcement to extend their lives. The bindings/spines of all paper items not prebound are reinforced in house when use merits.
Weeding is an important aspect of collection maintenance. A systematic program of weeding superseded editions and broken files of unindexed journals is carried out routinely by the library staff. The faculty is requested periodically through department heads to review their areas of interest and instruction and to suggest for removal obsolete and worn materials. The library staff also makes periodic reviews of various sections of the collection in order to weed and remove such materials. However, no material is ultimately discarded without consultation with faculty most directly concerned with those materials. Final disposal of such materials (sale, exchange, discard or storage) rests with the librarian.
In order to facilitate the matter of routine weeding the following guidelines may provide help in making withdrawal decisions.
- Physical condition
- Book is worn or damaged beyond repair or rebinding;
- Paper may be yellow, brown or brittle.
- Bad formats - small print, cramped margins, poor illustrations.
- Content
- Information is obsolete, inaccurate, or poorly written.
- Newer edition is available in library or may be ordered. (In some cases older editions may be kept if they contain information not in newer editions or if use is determined to merit keeping old edition.)
- Material is sexist, harmful, and useless.
- Age
Generally the age of a book should not be the determining factor unless it falls within other guidelines for weeding. However, the following guidelines may be useful in making decisions.
- Ordinary texts over 10 years old.
- Science and technology after 10 years.
- Travel books after 10 years (except Badeaker).
- Business books between 5 - 10 years.
- Humanities may be candidates after 10 -15 years.
- Language
With the exception of dictionaries, materials in a language not taught in curriculum should not be retained.
- Duplicates
Generally only one copy of a title is purchased/added unless anticipated use warrants.
- Unneeded duplicate titles (based on use patters, assignments, etc.)
- Paperbacks in poor condition unless demand merits keeping.
- Editions in languages other than English unless language is taught.
- Special cases that may be considered
- Materials replaced or available in another format (e.g. microforms to replace periodicals in hard copy or little used individual titles.)
- Old general or school dictionaries.
- Old grammars (except for historical comparison, etc.)
- Materials which no longer relate to academic curriculum or extra curricula enrichment.
- Older purely inspiration literature, popular self-help psychology, and textbooks.
- Use patterns
In general, use, like age, should not be determining factor for weeding unless material falls also within other guidelines for withdrawal. The following criteria may be useful in making decisions if lack of use should become a key factor.
- Books that have not circulated at all unless considered references or are a standard or classic title.
- Books that have not circulated for last 10 years unless a standard or classic title.
- General guidelines for keeping a title
- Listed in a standard bibliography (BIP, EGLI specialized subject bibliographies or indexes such as Poetry Explication)
- Rare items
- Local history, author, or interest item
- Circulation record merits
- Only material on a subject in library or available.
- Sequels or books dependent or related to other works being kept
- Research value
