Searching for SF?

I like Science (aka Speculative) Fiction for its ideas.
If you want information on the authors, titles, series, dates, etc., of published works, try:
The Internet Speculative Fiction Database www.sfsite.com/isfdb
Contento's Index to Science Fiction Anthologies and Collections www2.best.com/~contento/0start.html
The Locus Index to Science Fiction (1984-1997) www.sff.net/locus/notes.html
