I know I've been absent for a long while. But I did not procrastinate: I decided to try to make a fuller comprehensive list of all the differences in term translation (an example here) in the Yen Press version of A Certain Magical Index. It will be kept up to date for every novel that comes out. I'm also thinking of taking requests, since I will probably forget some things.

Without further ado:
