Star Trek Series Bibles Available to Read

In a bit of surprise move, Paramount via StarTrek.com has released the series bibles for four Star Trek shows.  I am not sure if series bibles are written anymore but it use to be pretty standard to create a document that would summarize the series themes, look and feel, characters, potential path the series will go and other relevant information to guide the show in its opening seasons and also help sell the shows to networks.   As such it can be interesting to read what the first concept of a show was versus what it became in the first season.   So head over to StarTrek.com and click the show title to download a PDF of the show bibles from The Next Generation, Deep Space Nine, Voyager, and Enterprise.
