I didn't like the IM Fell English font used for body text and small headlines, It clearly wasn't made for those sizes. I made comparisons and was happily surprised that IM Fell is a total rip-off of famous
Garamond! So I'd suggest to use size and web proofed Garamond for body text. Adobe charges USD29 for single weight, but there are tons of various quality free versions online, I could look into that. Also, if you were open to ideas, I could make a mock-up of IMHO more unified design for the page, when i'll be back home in 2 days . As Post Captain said, no modern stuff preffered,
Bodoni would be excellent match for Garamond and could be used for headlines, where grungyness of IM Fell is still rather distracting. It's also very period-evoking, even being from 1790, you could see similar fashion in hand-written annotations for maps since at least 1730.
