The Tolkien Art Index
The Tolkien Art Index is live! 463 pieces of art by J.R.R. Tolkien are listed — essentially, everything that has been published that is even tangentially related to Middle-earth.
At this point, there are titles, descriptions, notes, tags, dates, cross-references — essentially everything except thumbnail versions of the images themselves. These are ready to add, but I must first secure permission to post them, and I have only just now initiated that process — so we’ll need to be patient!
I hope this will be of use to the Tolkien research community. Please do let me know if anything seems awry!
