1952M. Taube in Amer. Documentation III. 213/2 The basic ideas of unit terms as a substitute for standard indexing for subject headings and logical combination and order as a substitute for..alphabetic cross-reference structures. 1953― et al. Studies in Compar. Indexing I. 5 We have used the name ‘coordinate indexing’ for this general method and the more specific name ‘Uniterm System’ to designate a particular manual application of coordinate indexing. 1961T. Landau Encycl. Librarianship (ed. 2) 100/1 Co-ordinate indexing..is based on the conception of the Uniterm... In the Uniterm system each book..or other item is numbered as it is received and..it is possible to gain an approximate idea of the date of any currently-published item from its serial number. The title, salient contents, etc.,..are then analysed into fundamental terms usually of one word each. These constitute the Uniterms. 1976Gloss. Documentation Terms (B.S.I.) 70 Uniterm, originally a single word selected from, and characterizing a part of the subject matter of, a document, for use in a co-ordinate indexing system. Now loosely used as a synonym for keyword or descriptor. |
