The easiest way to get paywalled data is to just pay for it. If you do, make sure to strip any identifying metadata before distribution. The big problem is where does the money come from? A charitable individual is the best option but unless someone wants to volunteer... If you take donations they should be secure. You are funding piracy after all. Of course, people who have already bought or intend to buy these things are a big help.
Also this must have been done on some sort of a scale before, collecting together whatever we can find and making a way to index and distribute it (even if it's just a big torrent) could be worthwhile. A larger system could encourage the people who buy these things to share with the rest of us. Theoretically they're sciency types who vaguely agree that information should be free and most people are fine with piracy anyway. There's a fair chance that all we really need to do is make it easy for them. The biggest problem with this would be stripping metadata but this is a technical problem, I'll write something about it soonish. Also I can't really say but they're probably not doing serious stenography with this, probably.
Most important is a source for the papers, it's nothing without them and they're what will attract more people with papers to share. Collecting what we can find will be very useful in the long run and it means that even if there is no long run we still get a nice torrent.
>>18387It's not really relevant to what you said but that gives me an idea. Universities probably have a lot of people in them who've paid for these types of things and it isn't that hard to get onto a university network. Just food for thought.
