I ran into some technical snags with this, but I have finally gotten Ars Historica into a print edition! You can get it through Bookshop.org (my current recommendation for supporting independent bookstores), Barnes and Noble, The Book Depository, or Amazon in the US or the UK. It joins Maps to Nowhere in the tiny but growing library of novella-sized short fiction collections on my bookshelf — my physical bookshelf, I mean — and the others will follow in due course!
