CGTextures is run by Marcel Vijfwinkel, a 3D artist, and he is striving to make it the best texture site on the web. He also has a few tutorials on the site.
I'm digging the new 70's book covers that have been recently added. Get a free membership at CGTextures.com. Try some of these textures in your 3D app or Video Copilot Element 3D.
