I recently entirely recoded cgbookcase.com and I thought it might be worth sharing here:
There are now 250 PBR textures available for free in different resolutions. The texture library is now much more searchable because you can filter by category, minimal resolution and by tags. Also, there's texture map previews and a tiling preview on each download page.
Of course, all textures are licensed as CC0 (which means you can do whatever you want with them).
