Can anyone give an update on what is still alive where?
I've been searching on alt.binaries.starwars and regular torrent sites, but I can't find over three or four releases...
AvP2008 (over on tehparadox) doesn't have much left either.
I'm still looking for quite a bunch:

BLAK0002: RETIRED - The Ewok Adventure LD transfer
BLAK0003: RETIRED - The Battle for Endor LD transfer
BLAK0004: Droids: The Adventures of R2-D2 and C-3PO
BLAK0014: PBS’s The Mythology of Star Wars
(is this the one found on BabyHub's preservation release?)
BLAK0016: The Forgotten Scenes
BLAK0017: The Making of Star Wars 1977 & SP FX: ESB - 1980

EDIT: alt.binaries.starwars actually seems to contain quite a few BLAK releases. I think I can have my collection grew substantially there.
