Chadwyck-Healey Inc. has announced the availability of seven major bibliographies on CD-ROM, most with both current and backfiles. The choices include the British National Bibliography, Bibliographie Nationale Francaise, Deutsche Bibliographie, Bibliografia Nacional Espaņola, British Library General Catalogue of Printed Books, Bibliography of Biography, and ISSN Register.
Current subscriptions for the national bibliographies range from $1,499 to $1,950 per year. Each includes several back years. Each subscription includes periodic (monthly, quarterly, or annually) cumulating updates. There is an extended backfile available for BNB for 1950-1985 at $7,250. The British Library General Catalogue cuts off at 1975 and is priced at $18,500. The Bibliography of Biography, which comes out only once a year, is priced at $449 per year.
Least familiar to many is likely to be the ISSN Register, called ISSN Compact in the CD-ROM version. It has extensive bibliographic information about 600,000 periodicals from 193 countries in 144 languages. The annual subscription price is $1,589.
