Full indexes by topic, keyword and individual workauthor form a complete subject-index, based on the indexes in source bibliographies. This is a complete bibliography of Arthurian literature to 1978, the result of five years' work by Professor Cedric Pickford and Dr Rex Last of the University of Hull. It consists of a complete alphabetical author-listing, with key numbers for each item, of all critical material recorded in the standard Arthurian bibliographies (Bruce, Modern Languages Quarterly, BBSIA and various other minor lists) with full indexes by topic, keyword and individual work,/author. The total is over 10,000 main entries, with all recorded reviews listed after each entry. Where summaries exist in BBSIA, this is indicated in the main entries. The computer programs have been specially devised and written for this bibliography by Dr Last, and programming and editing of the material has taken morethan two years. Updating volumes are planned to appear at five-year intervals.
