An exhaustive bibliography of some SF authors but with good detail is at ISFDB.
The complete works of Sydney Fowler Wright || Wayback archived copy of SFW site, which is often down. (enable javascript for the archived links to work correctly).
There is an extensive bibliography available at Center for the Study of Science Fiction.
Useful introduction to Science Fiction from wikipedia.
The boundary between tv and film is now quite blurred. An excellent introductory article on film and science fiction is at Wikipedia.
Also filmsite.org also have a good introductory article on science fiction and films.
Wikipedia has a good article about SF on TV.
tv.com has many pages on lots of tv shows which are more or less science fiction related - their definition is quite broad - and if you browse without javascript (very wise!) you can ignore their stupid red warning telling you to turn javascript on.
BABYLON 5
jmsNews has archived ALL of jms news posts where he discussed the writing and production of the show in searchable form....
The Lurkers Guide although long a dormant web site still has a great deal of info. on Babyon 5.
Try the data held on TV.com Babylon 5 and if you browse without javascript (most wise) ignore their stupid red warning that javascript is required.
The Zoccolo/ ISN News has a large section B5 info -ISNNews
Visit Bill Mumy [Lenier]'s web site. I have the lyrics of a song by Bill Mumy
about cats.
STAR TREK
Currently (tm) CBS Studios Inc.
There is a specialised Star Trek wiki (enyclopaedia) at Memory Alpha with over 26,000 Trek related articles.
TV.com has a lot of info on Classic Trek and even more on TV.com- The Next Generation not to
mention TV.com Deep Space 9. You can ignore tv.com's stupid red message insisting on javascript.
At last in mid-2010 CBS have relaunched the old startrek.com web site, and updated it. Lots of information to be found in the Startrek database section. The Animated series is now listed in the section as canon (it was previously denied that honour). Most parts of the new site work fine but if you select the link to "explore the official database" or a "view all" link, it takes you to an unfriendly "navigator" section which requires javascript. I cannot obtain any results from the search box. Other links seem to work fine right now.
Three cheers for Star Trek Animated series! Check out Curt Danhauser's web site. And for some fun, StarTrekAnimated.com.
