Some of the scans that you can find in Reading Room section were released by Retromags team. I usually get all this things from my friends and due to lack of time and/or being lazy I don't trace where was it released originally... unless the person who released it contact me. So let's say a big THANK YOU to the Retromags team! They work hard!
You can visit Retromags website and check what they have to offer:
