I'm wondering whether the official treatment or series bible has been published for any/all of the following television shows:
- Buffy the Vampire Slayer
- Angel
- Firefly
- Dollhouse
While screenplays and script books for these shows seem easy to come by, I haven't had any luck finding a published treatment or series bible, nor any indication whether those documents exist (I would assume that they do exist, albeit probably stored in an attic somewhere).
To be specific, by "treatment," I'm referring to the document that would have been used to initially pitch the show to the television networks.
And by "series bible," I'm referring to the official guidebook that would have been used by the show's screenwriters as a canonical reference to the show's intent, its main themes, character histories, mythology and so on. (Do a web search for "Battlestar Galactica series bible" to see an interesting example of one of these.)
Note: I'm not interested in any sort of fan-created synopsis, merchandise item, transcript, or marketing material that was created after the show was aired. I'm only interested in whether the original documents are available to the public in some format and, if so, where to get them.
