This CD-ROM edition of The Encyclopedia of Science Fiction differs from the 1993 book text in two ways. (1) We have corrected all the 1993 errors which we have ourselves discovered, or which have been brought to our attention through the ongoing conversation we have been privileged to conduct with scores – more like hundreds – of correspondents and colleagues. We have also added information such as dates where we had missed them, or where they had not previously been brought to light. (2) We have updated the body of the work from mid-1992 to approximately the end of 1994 (a few important 1995 dates and items have been admitted as well). There are approximately 25,000 words of new entries, ranging over the entire range of the book; and (we can only make a guess at this point, as these new words have been woven into the texture of the existing book) perhaps as many words again added to update previous entries. The areas of the book in which the updates are concentrated are Authors, Awards, Films, Magazines, Television and some Themes. As the 1993 book edition was probably closer to 1,350,000 words than the 1,300,000 we calculated hurriedly at the time, this brings the total length of the book to around 1,400,000 words. [A later computer count corrected these totals to 1,311,108 words and 1,378,261 words.]
A book like this can only be truly and happily successful if it is understood to be part of this ongoing conversation about the field. Our debts to all those who have taken part in this conversation are as before; only larger. We would like, too, to thank all those who voted for us in the many awards, including the Hugo, which the 1993 book edition won.
We intend to continue revising and updating our sf data with future editions. As before, so now, we deeply appreciate all the help we can get. Letters can, of course, be sent via our publishers; or suggestions and corrections about author entries can be sent directly to John Clute, 221b Camden High Street, London NW1 7BU, England, and about all other entries to Peter Nicholls, 26A Wandsworth Road, Surrey Hills, Victoria 3127, Australia.
