Nicholas Harrison

Open publisher page 0 citations

Abstract

An outline is given of the various conventional legal information sources both primary and secondary. Examples are given of the use made of judgments and rulings. The format, content and application of such sources are explained, and the need for computer‐based systems discussed. The LEXIS system, launched by Mead Data Control in the USA in 1973 and in the UK in 1980 is introduced. Details are given of the LEXIS libraries (law relating to particular jurisdictions) and file structures. The search logic is demonstrated with examples of search profiles and strategy. There are three sample printouts. No refs.
