Now where did I put that copy of the Necronomicon...?

I did find some old books at the inn, but not the one for which I was looking...

I did find two arithmetic books and one (elementary school, not abstract) algebra book printed in the 1840s. They
had word problems in which one had to give the answer in bales...

There was also a dictionary from the 1890s, but that was much less interesting.
