Abstract

Online offers the advantage over CD-ROM and locally loaded databases of being able to search several databases simultaneously. However, even when different databases have common fields, they may be named differently. This is improving, particularly throught he efforts of Mead Data Central and DIALOG. Discusses searching single databases; 2 ways in which online systems standardise fields; the lack of standardisation in the field tag SF=; Dialog's standardisation; generic field designs; standardisation of field content and NEXIS and uniform segmentation
