To be honest, I'd be okay with scanning 401 pages if I could get something out of it. I mentioned here that I wish there was a website where you could get credits for the number of pages you scan and then use these credits to pay others (perhaps with a rating system for getting the correct item, speed, quality of scan, etc.). Might not be that hard to set up, actually, but I don't have the time to do it.
You're probably aware, but for those who aren't, WorldCat is a good way to see which libraries near you have which books. Unfortunately, participation of libraries outside of the US, Canada, Europe, and Australia seems to be incomplete, but at least some Colombian libraries participate. Another problem is that not all of the holdings of some particular libraries seem to be in WorldCat. The Library of Congress in particular seems to have problems with this for some more obscure items. I've gotten into the habit of checking the Library of Congress' catalog separately.
Over the last year, VincentYu, gwern and others have provided many papers for the LessWrong community (87% success rate in 2012) through previous help desk threads. We originally intended to provide editing, research and general troubleshooting help, but article downloads are by far the most requested service.
If you're doing a LessWrong relevant project we want to help you. If you need help accessing a journal article or academic book chapter, we can get it for you. If you need some research or writing help, we can help there too.
Turnaround times for articles published in the last 20 years or so is usually less than a day. Older articles often take a couple days.
