Title
Automated pre-coding of free-floating subdivisions in subject authority control at the University of North Florida Libraries

Abstract
The Library of Congress Subject Headings scheme contains a system of free floating subdicisions under types of subject headings. To create an authority record for each actual use of each subdivision would cause a great deal of extra work and lead to an excessively large authority file. On the other hand, the use of subdivisions is a hindrance to automatic verification of headings, since there is usually no corresponding authority record to which a heading with subdivision can be matched. Describes a method of automatically pre comparing subject subdivisions with verifying lists and shows how precomparisons of subdivisions can be made automatically until, and if, the problem of free floating subdivisions in automated subject authority control is externally resolved.
