I stumbled across a site called "Victorian Days." It is an offshoot of www.AngelPig.net. Apparently it started out as a Barbecue site, that branched out into Southern culture and then got into Victorian society. Rather than the meandering endeavor this might imply, I'm thinking it's a genius with too much in their brain to stay focused on just one subject.
The Victorian sideline is more extensive than most folks would attempt as a mainline. The site map shows dozens of subjects on Victorian culture and etiquette. Each has at the bottom of its page more detailed articles on the topic. I'm not sure how many items there are, but you could spend all day reading. They are well written and appear to be well researched.
