Book excerpt: The field of information retrieval, the methods of indexing and storing the vast number of scientific documents which have been produced in recent years is surveyed. Information retrieval utilizes coordinate indexing - that is, listing documents under all the topics they contain and searching for them by two or more terms. There are two principal types of indexing: one using a predetermined list of terms into which all documents must be fitted and the other allowing free choice of the terms found in the documents themselves. Elaboration of these methods and the difficulty of developing a list of indexing terms are also discussed. An information retrieval system may consist of an index only, an index with an abstract, or an entire document with an index. The mechanical equipment used may range from punched cards through IBM cards to complex computers and micro photographic systems. The experiences of various organizations with different combinations of equipment and methods are discussed.

Available in PDF, EPUB and Kindle. Book excerpt: In response to many inquiries from users of the Thesaurus of ASTIA Descriptors and from others interested in the use of controlled vocabularies for mechanized information retrieval, this paper is offered as an outline of the general plan to be followed in the preparation of a Second Edition of the ASTIA Thesaurus. The philosophies of the descriptor and thesaurus approaches to information retrieval are discussed, with particular emphasis on the relationships among descriptors. Although this document was intended as a guide line for individuals who had been invited to participate in the preparation of the Second Edition, the discussion of the thesaurus philosophy is believed to be of general interest to documentalists. Included is a bibliography which cites papers dealing with the general concept of technical vocabularies.(Author).
