A reading list?

Since nobody started this, I think I will.

I did a tag-mash on "alternative history" minus "fiction" and got:

A lot of interesting-sounding books on that list. Anyone read any of them?

One dealing with alternate history is the third Pendragon book. Part of it has to do with the Hindenberg being destroyed.
