This paper provides some perspective on the history of information retrieval that had its beginnings long before the creation of the Internet and provides some enlightened predictions on possible future directions of the field.ABSTRACT | This paper describes a brief history of the research and development of information retrieval systems starting with the creation of electromechanical searching devices, through to the early adoption of computers to search for items that are relevant to a user's query. The advances achieved by information retrieval researchers from the 1950s through to the present day are detailed next, focusing on the process of locating relevant information. The paper closes with speculation on where the future of information retrieval lies.

“…It allows greater flexibility and precision than most systems and is adaptable to both manual and machine use. Its application to the indexing of a small collection of articles was described by Wilkinson (1959), and its capabilities were explored in detail by Taube and associates (1953Taube and associates ( , 1954Taube and associates ( , 1956Taube and associates ( , 1957Taube and associates ( , 1958. Zatocoding, a relatively simple system in which a machine sorts marginal punched cards, was described by Shera, Kent, and Perry (1957) and in detail by Mooers (1956).…”

The display of a Dual Dictionary on microfilm is com-Pact and easy to use. Each frame includes the name of a descriptor and 10 columns Of numbers representing the documents to which the descriptors were applied. The numbers are assigned to the columns on the basis of the value of the unit digit. Kodamatic indexer lines may be included. A set of computer programs has been written to produce a Dual Dictionary on microfilm. The index is readily updated and replicated. Furthermore, the program accommodates a dictionary or document collection of any size. Dual-Dictionary displays have been generated for a chemical fragment index, including 70,000 compounds averaging 5 fragments Per compound, and for Sev-era1 smaller collections of reports and other data.
