I thought I had it all figured out - Google offers 100MB storage on Google Sites and SkyDrive offers like a gazillion GB free storage. I thought I would upload all the PDF files to SkyDrive and only manage the HTML files and the links using Google Sites. Alas, SkyDrive (those bastards!) change the public links everyday! So the links I first posted here only worked for a very limited amount of time.

The good news are I think I found a new storage provider that does not change its links. I will be updating the site during the next week. So keep checking it out...
