Philosophical bases of subject cataloging

•Subject cataloging, like many library activities, is concerned mainly with organizing knowledge for effective use.
•The cataloger first determines the significant characteristics of a work,
• and then translates the subject content into terms of the systems being used --the notation of the classification scheme and terms selected from the library’s authorized subject vocabulary.
•The nature of the work and library’s policies guide the cataloger's decisions regarding specificity and depth of analysis .
