This list looked like it was trying (but failing) to be in alphabetical order. I contemplated arranging by Author, but since it was already semi-sorted by Title, I just went with that.
I believe it was originally alphabetical, but while still keeping the classics and contemporary separate. But users removing things and changing things got it all out of whack.
I guess that sort of makes sense since they were divided as such on the original website, but I think it’s easier to deal with this way.
