I've sorted the collection into the following piles. These are rough numbers.
100 Lisa (many backups)
20 IIgs
40 Commercial titles (Microsoft, Virex, etc)
75 Apple commercial titles (standard system disks, MacPaint, MacWrite)
40 QuickMail commercial disks. Looks like a pile that an IT person would have kept to prove they were licensed
100 Software development, mostly hand-labeled disks, including source code. Seems like he wrote "MacCheque", "MacDesk", and "MacPhone" circa mid 1984.
50 blank disks (40 sealed NOS)
175 misc hand-labeled mixed files
100 already copied. Half are the titles I've posted to this thread. Half are backup copies of those.
As expected, a good portion of the disks are backups or already archived common titles (Apple system software, etc). I get the impression that these are from at least two different original owners. I bought the collection on eBay.
For my next step, I'm going to cherry pick the most unique looking disks and randomly sample some from each pile. There is no way of knowing whether the label matches the contents without going through each disk.
In the end, I'm hopeful that we'll end up with a couple of dozen of novel items that truly add to the archives.
