This is a must-have for any serious science fiction fan with an Internet connection.

You'll find pages loaded with information on favorite science fiction writers, actors, and directors. There are sites devoted to science fiction in movies and television series, authors, cult favorites, novels, comic books, you name it. The selection of "supersites" alone make this book a very worthwhile resource for anyone interested in fantasy, horror, or the paranormal as well as straight science fiction.
