The trial transcripts, etc. are available at

There are two HBO documentaries on the case:
Paradise Lost: The Child Murders at Robin Hood Hills and
Paradise Lost 2: Revelations which I think are available on youtube in multiple parts or which can be purchased on Amazon.
At least two books have been written on the case.
Devil's Knot is a well-documented although slightly dated book. The author, Mara Leveritt (sp?), is currently working on a sequel.
The Blood of Innocents (sorry, I don't remember the authors) is a little more sensationalistic, but still contains some good information. I believe both books can be purchased through Amazon.
Apparently, you saw the
48 Hours episode. CNN recently did a show on the case,
Presumed Guilty. I don't believe the video for that is available online, but the transcript is. It is on CNN's website. There have been other shows over the years, but many of them are old and dated. Some of the others are discussed (some links are even posted) on the blackboard site.
There are many discussion boards about the case also. IMO the most informative of these is at
www.wm3blackboard.com. This board believes in the innocence of the convicted young men and makes no bones about it. Another board, which believes that the convicted are guilty and makes no bones about it is
www.wm3hoax.downonthefarm.com or something like that. I'm sure one of the posters here will correct that url if I got it wrong. I must warn you that they are rude and crude on that board, as you will readily see for yourself if you post there for any length of time.
This case ignites passion in all who follow it, and many times, as you will see on this site, that passion leads to heated debate. At least on this site, the debate is courteous. I can't say the same about other sites, except the blackboard site.
Where the case stands now is awaiting the recently-ordered evidentiary hearing. In September, 2010, oral arguments were made in front of the Arkansas Supreme Court on behalf of Damien Echols requesting an evidentiary hearing based on new testing of biological evidence that excludes Echols and the other convicted men. In November, 2010, in a unanimous decision, the ASSC ruled that not only Echols but the other two defendants as well were entitled to an evidentiary hearing to present the new testing results as well as other facts and statements that have come to light over the years since the original trial. I believe the oral argument video is still available at the blackboard site I cited earlier. The evidentiary hearing has not yet been scheduled but is expected to be in October of this year.
Damien Echols has also published a book since being incarcerated called
Almost Home. Off the top of my head, that's the best I can do to direct you to information on the case. Please ask questions as you read, and I will attempt to answer them. I have followed this case since 1996 when the first HBO documentary was aired, and I firmly believe in the innocence of the men in prison. There are other posters here who believe that the men in prison are guilty, and I'm sure that they will give you their perspective as well.
