One of the Library Users pointed me to a complete collection of Scientific American from 1845 through 1909.
While I was perusing those and checking the copyright status of them I happened to run across a collection of Popular Science magazine from 1870 up through modern times. Not sure on the copyright status of the more recent ones but the ones up through the early 1900s should be in the Public Domain by now.
I’ve run into few couple instances where scanned books I’ve downloaded from public sites and even University Libraries turned out ot NOT be in the Public Domain but still in active publication and under copyright. You’d think that a University Library would be a bit more careful but surprisingly that doesn’t appear to be the case. So I have to spend a bit more time these days checking copyrights of books before posting them.
It’s going to take some time to get them all downloaded and cataloged since were talking about roughly 2800 Scientific Americans issues and probably at least a couple thousand Popular Science issues.
I don’t know how long it will take to get them all added, several weeks at least. I may put partial batches of them online as I reach certain ranges but that will depend on how much work is required to get the cataloged and loaded.
But a heads up at least.
