Interesting stuff.
I am new to this scene so take my comments with a grain of salt. I know photographers (and other artists) are very sensitive about copyright blah blah blah. Personally, I am against all forms of copyright. That's not going to elicit any warm feelings on here, I know.
It seems a crime that there is this information out there that people have to wait for some corporation to grant rights for it to be released. Absurdity is the word that comes to mind. If I had a copy of these newsletters, you can bet I'd scan them and put them on bittorrent ASAP. Knowledge should be free.
