A few resources that you can be interested in.
Georgian LondonAn awarded, admired and - last but not least - nice to read blog, though personally I'm a bit annoyed with the author's manner of avoiding any citations and resource notes. But the blog is still a very, ahem, inspiring site, with its sections such as 'Criminal London' or 'Sick London' or 'Hogart's London'... You can also find there highly interesting and rare graphics, like a map of London molly houses or a nice collection of handbills or medical drawings from a pregnant woman's autopsy... Hmm, that's why I probably should put a warning here: an R-rated resource. Or NC-17?
The Trans-Atlantic Slave Trade DatabaseA GORGEOUS RESOURCE! No, really. You can find there not only stats, but track down every single voyage - vessels' and captains' names, flags, dates, ports of call... Also maps and images. There are also personal details of enslaved people.
Matthew Fontaine Maury's Whale ChartA reprint of a world's map from 1851, made for whalers. The same company published also a reprint from the verge of Age of Sail, depicting
History of Panama Canal, veeery nice for an eye!
