Is there anywhere on the internet that I can read *official* shooting
scripts for Season 7 (the current season) of Buffy the Vampire Slayer?
I have found unofficial sites (some that look pretty official but for
the disclaimer), and sites for old seasons. What I am looking for are
the official shooting scripts for the couple of episodes that have
aired so far this season.

Greetings!  Usually, an official shooting script is not available
until a season had ended.  Your best bet would be to join a
screenwriting or teleplay writing message board and network for the
scripts.

Script selling is a big business so try Ebay.  Often housekeepers
remove them waste cans in actors residences to resell or they walk off
the sets pilfered by extras or retrieved from waste cans there.

The unofficial site you mentioned is probably your best bet at
present.  Many times fans will watch the tapes of a show over and over
to render the shooting scripts for their own collections.

You might want to try http://studiesinwords.de in the future. However,
they are currently on hiatus and nothing comes up if you go there now.
