Someone is ripping off the NZVRS library and selling it...

twitter.com/oldschematics is his Twitter.

Obviously I'm new here - just met Ray51 today. My take is that all of these things are in danger of being lost forever, as many copies as possible distributed everywhere is a net benefit. Taking a look at that list - there's an enormous amount of stuff there, a lot of time. He seems to get only 2 page views a day, and only has 3 followers on Twitter. In a technical sense - anything after 1919 became automatically copyrighted by the artist/designer(you weren't required to put that funny "C" in a circle after 1919), so the schematics may technically still belong to their original owners(or wherever those assets were sold), so even scanning them and distributing for free is an infringement! Depending on how they are classified this could extend till 50 years after the schematic drawer died.

To be totally above board you can copy it, but you have to redraw the circuit yourself. There's also a counter argument that because these were designed for mass distribution they were released into the public domain, although that's not necessarily guaranteed. Thankfully this stuff isn't a problem in practice!!! So everyone's either collectively guilty, or collectively innocent Haha!

I appreciate your work by the way!
Cheers.
