Mary Catelli's Erraticly Updated and Exceedingly Ill-Organized Journal

For a good guide to things steampunk and/or Victorian, may I recommend Bill Stoddard's GURPS Steampunk. Has information on the Victorian period, steampunk memes and tropes, and guides to creating a steampunk milieu. As with other GURPS supplements it is well researched and can be used for projects other than a GURPS game.
