CENTRALISED CATALOGUING
By centralized cataloguing, we mean the provision of cataloguing service from a central point to several clients. The service may range from a simple cataloguing of documents to complete and whole cataloguing with the preparation of catalogue cards ready to be inserted into the clients catalogues.
In simple terms Needham defines centralized cataloguing as "the cataloguing of documents by some central organisation". The main purpose of centralised cataloguing is to save duplication of effort in the cataloguing department of several libraries.
