Much lauded. A broad overview, from Roman times to the present, divided chronologically.
Guidebooks and Atlases
Guidebooks and atlases of London in the late 19th century are exceedingly useful, and not at all hard to find. By far the best is Bacon's atlas, but it is quite expensive and has nothing but maps. Any of the hundreds of different guidebooks will give you lots of detail; Muirhead's is nice because it also gives you complete floor-plans of places like the British Museum.
Bacon, G. W. “Portable” Atlas of London (ca. 1910)
———. New Large Scale Ordnance Atlas of London (original edition 1888)
———. The A to Z of Victorian London (Bacon’s atlas, with introductory notes by Ralph Hyde)
Baedeker’s Guides (to London or England) from this period, and there were many, are very useful.
Dickens, Charles Jr. Dickens's Dictionary of London 1888: An Unconventional Handbook and Dictionary of the Thames.
Fantastically useful, especially the Dictionary of London, for all sorts of trivia and small bits of ordinary life. The reprint is a lovely facsimile in cheap hardcover -- get one now!
Muirhead, Findlay and L. Russell. Muirhead’s London, early editions preferable.
If you have a modern London A to Z, less has changed than you’d think, but the whole East End is very different, as are Leather Hill and the other major rookeries. That’s urban renewal, folks!

I have the 1907 version, which is still quite useful for the Victorian Age, but if you want to spend a bit of money (anywhere from 40.00 to 200.00), you can purchase versions dating from 1887 – 1899 that are even better. Baedeker guides are invaluable if your characters are traveling throughout the country)."] Rare.
