@FelicityBeedle and anyone else who likes social history, if you read 19thc novels in general, you might love Judith Flanders' The Victorian House -- which is a brilliant chunk of social history on Victorian domesticity, and wonderfully dippable-into. She goes around a Victorian house (basing herself on the middle classes, but with excursions up and down the social scale) and in bedroom, parlour, scullery, breakfast room, sickroom, nursery, dining room, bathroom, kitchen etc, she basically analyses what people did, ate, wore, worked, their hobbies, social lives etc. There are fascinating descriptions of Victorian laundry, courtship, mourning clothes and the rules of mourning, visiting cards, relationships between mistress and servants, the growth of suburbs, the treatment of illness, childrearing practices, as well as heating, lighting, sanitation, home decoration fashions etc etc.
It illuminates all kinds of things about 19thc fiction, and made me understand things in fiction I'd never thought much about, like why Katy Carr has most of the furniture and the carpet and curtains removed from Amy Ashe's hotel room when she's ill, and has the floor scrubbed with soap and the bed pulled out from the wall, or why Mrs Fairfax has to hand over the keys of the storeroom to enable the servant to make a meal for Jane Eyre when she arrives at Thornfield..
The other one I'd recommend from a social history perspective is Jane Austen and Food by Maggie Lane, which is brilliant on the things Austen does with food, meals etc which would have been understood by her contemporary readers -- like the significance of the big difference between the Longbourn breakfast time and the Netherfield one, or what the significance of the fruit served at Pemberley is.
Virginia Nicholson's Singled Out is also very good on the very interesting lives of the 'Surplus Women' who would have expected to marry, but whose potential pool of men was decimated by WWI, and what they did instead -- some of the CS mistresses would have been from this demographic.
