The Annotated Sherlock Holmes by William S. Baring-Gould is one of my most prized possessions. I have the single volume edition and I’m sure someone somewhere has written a mystery where this book has been the blunt instrument. Sadly it is out of print, although you can find used copies for sale at Barnes&Noble and Amazon or your local antiquarian bookshop (a shout out to the Hermitage in Denver).
Sadly it can be difficult to find the Baring-Gould annotated Holmes and Holmes scholarship continues, so you may be interested in the New Annotated Sherlock Holmes, edited by Leslie S. Klinger. Two volumes address the short stories and the third volume covers the novels. I unfortunately only own the third volume as a reviewer’s copy.
Gasogene Press calls itself “the premiere publisher of books about Sherlock Holmes and his world. We have assembled a broad array of titles sure to appeal to the discriminating reader. Whether you’ve just discovered The Great Detective or you’re a seasoned Sherlockian, we’re sure you’ll find many unique volumes to pique your interest.
To honour the author and his works, the Metropolitan Toronto Reference Library, now the Toronto Reference Library (TRL), established the Arthur Conan Doyle Collection, one of the world’s finest collections of material by and about Sir Arthur Conan Doyle available to the public.
Oh snap! my world just expanded again. I found Victoriana magazine and now I am forever undone. This free online magazine is a beautiful resource for all things Victorian. Prepare to get lost.
I needed to know how many mail deliveries a day the Victorians expected and may have found it here (a New York Times article had a different number for a period closer to Holmes), but regardless I was still happily lost myself exploring The Victorian Dictionary.
Almost as important to Holmes as his Bradshaw’s are Debrett’s Peerage and Baronetage, since 1780 (with a few lapses) the who’s who of the English titled, and Burke’s Peerage, Baronetage & Knightage, first published in 1826. InThe Noble Bachelor, Holmes “picked a red-covered volume 
from a line of books of reference beside the mantelpiece” and read an entry for Lord Robert Walsingham de Vere St. Simon. I cannot say that either of these references are canon, because both sport red covers, but I think collectivley they are. It is not inconceivable that Holmes owned both.
The Science of Sherlock Holmes does not directly examine the science mentioned in the stories and novels but instead is more of a history of detection and forensic science and the parallels with the Canon. Here you will learn of Alphonse Bertillon and Eugène François Vidocq of the Sûreté, and Conan Doyle’s own investigations, as well as the notorious crimes of Dr. Hawley Crippen and the sloppy forensics in the Jack the Ripper investigation. Despite not being an annotated science of the Canon, it is an invaluable resource.
If you’re writing your Holmes pastiche, you’ll need a good map of London by your side. I found the link to Mapco at the Nashville Scholars website. The map site is free and takes donations. You may also wish to visit the associated Old London Maps.
While stumbling around the internet, I found the Victoria Research Web, which is kind of a howto for Victorian research: “The various sections of the VRW are intended to supply advice and links to help Victorianists find the practical information they need, whether it’s an archive catalogue, a bibliography, a listserv address, a sample syllabus, a cheap place to stay in London, or a journal’s submission guidelines.” It’s sort of a place where you don’t necessarily find the answer, but instead where you can begin to understand how to pose the question.
According to the website: “London Historians was launched in August 2010 as a club for Londoners who’d like to learn more about their city’s history,” but even non Londoners can follow along through the website and blog and twitter.
