yea, I clicked on this earlier and it didn't seem helpful. Just now however, I explored it again and there is a ton of information on there; more than I can comprehend at this point. Click on the archive button and there are a bunch of links then some of those have sub links. I downloaded and entire book on organic synthesis of drugs (didn't read any of it but it sounded cool I guess). There are more books as well to download for free. Click away.
