If you have not already read my Disclaimer & Credit page, I suggest you do. As stated there, this is a Fantasy Game and is not one intended to be historically accurate. Further, nothing on this site (or any of my game sites) are created for personal gain or profit. It serves entirely as a playing aid for those participating in my games.
As is immediately obvious to anyone who has played AD&D, I must give credit to TSR’s Advanced Dungeons and Dragons (First Edition) for the basic structure of the game. Along with WOTC’s 3rd edition. And Advanced Dungeons and Dragons 3.5 and the D20 variants for many modification ideas. Also, TSR’s Boot Hill for some equipment lists and Trent Foster’s Advanced Dungeons & Dragons Companion, A Collection of House Rules and Expansions.
Additionally I must credit Steve Jackson’s G.U.R.P.S. Generic Universal Role Playing System (1st through 3rd) for many of the ideas regarding timing, skills and skill points. Along with G.U.R.P.S. Deadlands and Weird West, primarily for weapon and equipment lists and ideas.
Living Death Campaign Sourcebook A d20 Adaptation of the Masque of the Red Death rules based on D&D version 3.5 by Claire Hoffman was of great help in working out much of the gun fight and explosive rules.
Call of Cthulhu particularly London 1- An Investigator’s Guide to London and London 2- A Keeper’s Guide to London along with Chaosium’s The Gaslight Equipment Catalogue. Which were essential for information on money, equipment and pricing. I have tried to edit out anything that did not exist prior to 1890 (the year the game starts.) And of course, Call of Cthulhu: Cthulhu by Gaslight: Horror Roleplaying in 1890s England
1879 Role Playing Game, Player’s Guide, 1879 Role Playing Game, Gamemaster’s Guide, 1879 Role Playing Game, London or the Haunted City were a big help in descriptions of places and parts of London.
There have been MANY websites, but of special value has been (as always) Wikipedia! If you can, please spare a few dollars to donate to this most worthy and valuable non-profit!
Other sites include, (but are not limited to!)
Victorian era England & Life of Victorians This has been an invaluable site that has scores of pages detailing Victorian life from Class, customs, laws, fashion, food, government, morals and more! I highly recommend it to anyone interested in the period.
I relied heavily on Victorian Domestic Hierarchy and Wages for much needed clarification regarding Servants and their lifestyles.
The Victorian School gave much insight on the Empire in its totality. Relative size of territories, population, etc.
Stanford’s Geological Library Map Of London And Its Suburbs 1878 provided me with a much needed grasp of Where Things Are and travel times.
The MAPCO Store was also invaluable.
Turnpike Roads in England and Wales was a great source of information on overland travel in Great Britain.
Another valuable source was Railways and Population Change in Industrializing England An Introduction to Historical GIS for determining population and rail travel within Great Britain.
For assistance in comparing the costs of goods in the UK vs the USA Androsphere Blog was very useful.
I cannot begin crediting authors and novels without first specifying Sir Arthur Conan Doyle’s ‘Sherlock Holmes’ series, which I have loved since childhood. And of course the many spinoffs and follow up novels (and movies and TV shows) by other authors (too numerous to remember much less credit!)
A few additional authors include, Wilkie Collins “The Diary of Anne Rodway” also Andrew Forrester’s, “Miss Gladden” and Leonard Merrick’s “Mr Bazalgette’s Agent.”
