A survey of automatic indexing systems and experiments has been colducted by the Research Standards. Consideration is first given to indexes compiled by or with the aid of machines, including citation indexes.

Advantages, disadvantages, and possibilities for modification and improvement are discussed. Experiments in automatic assignment indexing summarized. Related research
