Abstract
Discusses the rapid increase in the availability of the full text of journals, newspapers, documents and books, online and in CD-ROM, in the recent past, noting that full text now makes up 49% of word oriented databases. Explains the differences between image files, ASCII fullt text which is searchable, and ASCII full text which is displayable and downloadable but not searchable, and gives examples of these. Highlights the full text databases which are being introduced by the H.W. Wilson Company
