Chadwyck‐Healey Ltd, Cambridge Place, Cambridge CB2 1NR proudly announces, in a six‐page brochure, its intention to issue the whole of the final London edition of The Guardian newspaper for 1990 in February 1991 on a CD‐ROM disk. Subsequently, disks will be issued quarterly within eight weeks after the end of each quarter, cumulating to the year end. All articles and editorial text will be on the disks but advertisements, sports statistics, racing results (other than in articles) and statistics, Stock Exchange prices, radio television and entertainment listings, are excluded as is some copyrighted material. However the complete front pages, including pictures and graphics will be on the disk and may be displayed in facsimile. Searching is available in novice or expert modes and, as is now usual, Boolean operators, right‐hand truncation, wildcard characters, adjacency and proximity facilities and range searching of numbers and dates may be used.
