"In 1950, Clavin Mooers described the problem as 'searching and retrieval of information from storage according to specification by subject', and coined the name informational retrieval.

The index has been in the form of subject headings, either printed in sequence on a page or typed on cards which are filed in sequence. During the past few decades new forms of index have come into use: cards on which subjects have been coded in patterns of holes, and, experimentally at least, paper tape, magnetic tape, magnetic drums and disks and photographic film. Such indexes are mechanically searched, and their development has been distinct from - almost in opposition to - traditional forms." This book (updated with new information regarding the fast changes in this area of computer science, especially in the 1960's) discusses the very wide open field of categorizing, indexing and retrieving information from computer systems with the varying theories described and discussed.
