Dayuhan, I do realize some of these books will be difficult or even impossible to get ahold of for some of the members here. However, researching and vetting enough sources to replace what one book covers is time I just don't have, unfortunately. If there are any hidden millionaires lurking who want to fund such an project, I'll gladly take their money!

With that said, I will definitely include academic articles and reference materials that are free and online in the future.
