This collection provides introductory information on technology and inventions,
medical sciences, engineering and allied operations, agriculture, home
economics and family living, management and auxiliary services, chemical
engineering, manufacturing, manufacturing for specific uses, and buildings.
This wide-ranging collection covers many topics. Coverage of the more
popular subjects such as medical sciences, agriculture and home economics,
and family living need to be broad in terms of reading level. Other subjects,
especially management and auxiliary services, chemical engineering, and
manufacturing are minimally developed because they are too specialized
and technical, and out of scope for children. Collection emphasis is on
keeping sources current and relevant to the interests and needs of the
young patron. Occasionally duplicate copies are purchased to satisfy patron
demand, but, in general, single copies are sufficient.
Purchases and buying patterns are determined in large part by:
- reading level.
- new works.
- budget constraints.
- circulation statistics.
- patron requests.
- shelf space.
- visual appeal.
- Titles with child appeal that continue to be used are considered for
- Physically worn materials are replaced or updated.
- Books are withdrawn due to damage, loss, drop in general interest
level as evidenced by circulation figures, or content relevancy and
- Titles with multiple copies are checked for usage, and duplicate copies
are withdrawn as demand decreases.
