An excellent site with a tremendous amount of links to everything you would need to get started in the field! It includes all facets of the field including patents, links, papers in PDF format and articles. I would estimate it to be no less then 50 and maybe as much as 150 different ones. The only little thing it lacks is maybe a short summary of what the different links leed to. But all in all, probably the best resource out there.
It will keep you reading for quite some time and the things I have read so far have been great.
