The map below is just a starting point. The author list is certainly not complete, and it would be awesome to be able to index authors by other maps as well, such as annual rainfall or soil type. (The map is also decidedly U.S.-centric.) If you have suggestions for other authors to include, or other useful formats, let us know in the comments section!

EDIT: Updated 2/22/15 to include Anna's suggestions. Thanks Anna! (And it only took us 13 months to get around to it!)
