Note that this list contains some authors whose works of fantastic fiction would today be called science fiction, even if they predate, or did not work in that genre. There is also a considerable overlap with the List of fantasy authors, since many authors are equally comfortable with both genres, and in any case some works deliberately combine the two or blur the distinction.

A great book for looking up authors is A Reader's Guide to Science Fiction by Baird Searles, Martin Last, Beth Meacham, and Michael Franklin. Even if it hasn't been updated since the 1979 publication at hand, it's very useful. It tells you whom else you might like if you like one author.
Also invaluable are The Encyclopedia of Science Fiction (2nd. Ed. 1991) ed. by John Clute and Peter Nicholls, and The Mammoth Encyclopedia of Science Fiction, ed. by George Mann (1999) (ISBN 0786708875 or ISBN 1841191779).
