Just FYI... as an archivist, generally when you have made (or we have made) copies of material under copyright (which is most non-governmental archival material from the 20th century), you should not be distributing it. I'm not myself liable if you do, but I'm required to give you a disclaimer when I make copies or allow you to make your own. Sometimes we have more expansive ability to grant permissions for reproduction, as governed by our donor agreement, like for several of our collections we either own copyright completely, or have an agreement with the donor to grant copyright permissions for just about anything, but mostly that's used to say "yes, you can print this photograph in your book." So, you know, only share your archives material with people you trust! If it ends up all over the web the archives knows who did it, and where you live... (Unless it's public domain, then just do whatever you want!)
