Probably the best place is Script City in Hollywood (or that general
area
).  They sell photocopies of scripts that were used by production
people on the set.  They have quite a collection, dating back to the
'30s and '40s (though more, of course, from recent years).  They
also have a lot of TV scripts.  I wish I had their address and/or
phone number, but it's been a long time since I've contacted them
and I don't have anything of theirs in my files.  Perhaps someone
else on the list has a catalog.
