The main objective of a classification scheme is to use a library management system to organize information resources from the computer onto the shelf based on tools required for bibliographic information resources. The process of this organization must be systematic in the way items are arranged in a library. So how this works for library catalogue? A classification scheme in a library catalogue such as an online public access catalogue system creates a link between an item call number for that record and item located on the shelf, this allows the screen interface to display a list of call number items as references to help users finalise these items at a fixed locations for example library shelves. What if we decide to automate a classification scheme instead?
Automating classification schemes based on organizing bibliographic items for library shelves poses a lot problems when using existing classification models. Firstly, the expanse nature of information resources on the web make it difficult but almost impossible to classify such resources, as well as time and cost. Secondly, any emerging or new subjects, particularly interdisciplinary subjects would compromise this scheme therefore it can only cater for small rather specialized collections. There have been attempts to introduce automated classification schemes before, for example, Cyber Dewey, and Cyber Stacks have gradually become redundant in use. However, digital libraries and subject gateways replicate a form of bibliographic classification scheme tool in organizing internet information resources, for example, BUBL and ACMDigital Library.
