The Fully Automatic Syntactically‐based Indexing of Text (FASIT) system represents the contents of a document without a full parse or semantic analysis of the text. Content‐bearing units are isolated and then grouped into quasi‐synonymous classes whose main term is used to index the document. Previous experiments with FASIT demonstrated its usefulness in an associational retrieval environment; the experiment described here explores FASIT's value as a book‐indexing system. It is difficult to avoid the conclusion that this indexing approach offers the promise of being practical and effective.
