] Most of the documents presented in this archive were
] discovered and secured by a known soviet dissident,

] in 1992.

One of the other members of my Kryptos brainstorming group discovered this webpage. It has PDFs of several KGB documents about dissident Sakharov, including a PDF of the same document that I found in the Sanborn folders of the Smithsonian Archive!

It's not clear whether my copy was obtained from the same dissident who got these copies, or whether they were two copies made on different days by two different people. But the archive is awesome, because it shows several different KGB documents, in their entirety, and in sequence. There are also other sections of the site which cover documents on other topics. If you want to see more KGB stuff, this is the place to go!
