Most archaeological organisations of the 20th century which produced grey literature sadly no longer exist (including most of the ones on my CV - hope there isn't a connection!) with a few more going in the 21st, so getting copyright permissions is just a little tricky, I've got one old site (from the 1970s) we can actually manage to publish properly as part of something else but no one around here now has heard of the original author, which is a touch awkward - D. Greenhalf, anyone?
