Items I have come across and scanned over the years that are believed to be of no/low copyright risk (defunct publications, etc.). I have a lot of newspaper articles and other items I will probably be nervous about posting for years to come, alas. For reference, I am a librarian who is quite familiar with copyright law, so even well-meaning suggestions about “the public domain” (something most people do not understand at all) will be taken with a grain of salt.)
