ABACUS-AB atomic energy computerized user-oriented services: the mechanization of bibliographic list production

This paper is a brief survey of the mechanization of bibliographic list production. A flow chart shows the methods used in processing document representations from various data bases (see Fig. 1 of the text). The ABACUS program package for producing combined acquisition lists for three science libraries from punched tape can also output a KWOT (keywords out of title) index on demand. The format of the document records, including ABACUS keys (see Table 1 of text), is discussed in detail. The paper also describes the error-detecting routines, and transformation of upper-case input into upper/lower-case output for producing a union list of periodicals. The paper discusses lack of standardization within the field and proposes ways to achieve interchangeability among document records. The ABACUS system is the result of cooperation between the Royal Institute of Technology and AB Atomenergi, Sweden.
