Among the things I turned up were original meeting notes for SFSFC board meetings and for Westercon Business Meetings (all since published in their final forms), as well as my meeting notices from the Interaction pre-con planning meeting last year. If I had much expectation of some future historian really wanting access to primary source documents, I'd keep more of this, but more than likely it's going to get recycled.
We're not done yet -- more work is planned for tomorrow when we'll tackle the computer area. California laws on disposal mean that I can't legally put into the dumpster an old defunct fax machine that we were lumbered with long ago and that has never worked. I wish I'd thrown it away back when it was legal to do so, because disposing of it legally now will be a pain in the neck.
