Subject Analysis:
Subject analysis is one of the longest established forms of added value in information services. It extends to the intellectual processes of indexing, classifying, cataloguing, abstracting, etc., which form much of the traditional activities of an information professional. The added value is claimed on the basis that intellectual input of the analysis makes the information much more easily accessible and the information store more comprehensible. Value would be added in terms of reduction in complexity of the access points. It must be emphasised that this sort of added value to information service costs money, and users may well not be willing to pay the premium for higher quality information.
