Automatic indexing and the various conditions that are to be met have been discussed. The definition of KWIC index, its origin and the method of its production have been delineated. Structure of KWIC index has been illustrated with the analogy of a horizontal wheel and a camera. It is stressed that continuity of the context at the extreme edges should be maintained whenever the beginning or the end of a title forms part of a KWIC entry. A modification in the output format of the KWIC index which can be called as the 'Altered KWIC' or AKWIC index has been suggested. Advantages of AKWIC over KWIC have been mentioned. Some of the limitations of KWIC and AKWIC have been pointed out. Permutation on titles and permutation on subject headings for the production of KWIC index have been compared. It is suggested that adoption of KWIC index by Indian periodicals and organizations should be encouraged.
