Procuding Uniterm catalogue by computer

Abstract

A program has been prepared for a Soviet-made Razdan-3 digital computer which is capable of processing library catalogue entries. Tbe program is many-sided. One of its possibilities is that the computer ignores the entries themselves and knows only the "clasaification scheme (tables)" and the groups of the related call numbers and claasification notations. In this case the computer sorts the numerical data according to the classification notations belonging to the call number, then it will draw forth the descriptor (i.e. the textual equivalent of the notation), from its store and will produce a Uniterm table so that it indicates not only the mere notation per item (by whicb the sorting and ordering operation was performed) but also the textual equivalent of the notation (descriptor).
The other possibility: Uniterm tables are not produced by the printer unit, but the output is a punched paper tape applicable to producing Uniterm cards on typewriter. In this case, for example an 8-channel paper tape may produce both upper and lower caae letters, discritical marks and symbols.
Further possibilities are provided by punched cards as output, and incidentally by such geomatxic formations which permit the production of Peek-a-boo cards.
Besides the "classification scheme", catalogue entries may also be fed into the machine. In this case, after ordering the above mentioned numerical data pairs (i.e. call number and notation), the machine is able to substitute not only descriptore for notations, but also entries for call numbers. Thus the ordering of data resolts in the sequence order of a "printed catalogue". Subsequently - now that it does not produce Uniterm cards - substituting headings for notations, and entries for call numbers, the computer may produoe - as output - a paper tape which is applicable for the machine setting of a publication.
