Very impressive! I tried doing something like this with all 3rd ed. monsters, sorted by CR and including a line or so of description, but I don't have nearly all the books. Any chance this is sorted by edition as well?
LordVyreth: Just play with the "Rules" filter at the top of the left-hand column. If you set that to "D&D3.5", it'll only show those entries. (For both 3.0 and 3.5 entries, you'll need to make a custom filter for rows containing "3".)
