Location of Materials
- Definition of Call Number Blocks
The University of Colorado at Boulder Libraries includes a variety of locations to which materials may be assigned. In order to make location of materials as predictable as possible to library users, and to facilitate processing, materials that are classified using Library of Congress Classification are assigned by "block" to particular locations, based on their classification number.
- Classification for Block
Materials are not specifically classified or reclassified in order to assure their location in a particular block (i.e. for a particular location).
- Out-of-Block Materials
Exceptions to block location are allowed for compelling reason. Thus, in addition to materials that "fall within block", individual Libraries locations may also contain some items, such as reference titles or certain other ancillary materials, whose call numbers do not fall within the block of numbers normally assigned to that location. Because by policy the Libraries holdings constitute one unified collection, and because financial and other considerations limit acquisition of duplicate materials, items located "out-of-block" are often the only copies of the titles held by the Libraries.
- Authorization for Assignment Out-of-Block
In general, materials are assigned to block location during cataloging by virtue of the classification number appropriate to the subject content. Location of an item out-of-block requries specific instructions from the librarian responsible for the non-block location, and approval from the librarian responsible for the block.
- Blocks by Location
New materials are assigned to location by block as follows (designations are for Library of Congress classification numbers or prefixes):
- Blocks by LC Classification Number
- Materials not classified in LCC
Materials not classified in Library of Congress Classification are assigned to location according to instructions from bibliographers.
