This collection provides introductory information on natural sciences,
mathematics, astronomy and allied sciences, physics, chemistry and
allied sciences, earth sciences, paleontology, paleozoology, life
sciences, botanical sciences, and zoological sciences. This is a
well- developed and well-used area that supports science fair projects
for the young patron. The 590s is also a well-developed collection
that meets the young patrons' interests in animals.
The primary goal of this collection is to provide introductory
information on the natural sciences and mathematics. Collection
emphasis is on keeping sources current and relevant to the interest
and needs of the younger patron. The collection strives to meet
the needs of younger patrons doing science fair projects. For the
younger patron, the Library:
- strives to provide a broad range of subject interests at varying
- evaluates patron requests either through reviews, or knowledge
and popularity of the author or title.
- purchases multiple copies of popular titles when patron demand
warrants and as budget allows.
- does not purchase textbooks and workbooks with practice sheets.
For the preschool through sixth grade reader the presentation of
information should include clear and colorful illustrations, highlighted
vocabulary, concise glossary, and an index (that may or may not
be present). Purchases and buying patterns are also determined in
large part by:
- reading level.
- new works.
- budget constraints.
- circulation statistics.
- patron requests.
- shelf space.
- visual appeal.
- The 500s contain subjects in which information is quickly dated
or even proven wrong (physics, astronomy, etc.), as well as subjects
where information is nearly timeless (mathematics). Therefore,
weeding must be aggressive in the more time-sensitive areas to
ensure the availability of accurate, up-to-date information, while
in other areas retention can be based more on condition and level
- Titles with multiple copies are checked for usage, and duplicate
copies are withdrawn as demand decreases.
