Recently I became involved in a conversation over on Facebook about a particular chronology book that I own but do not feature on the Page or here. That book is A Day-by-Day Chronology of Mr. Sherlock Holmes: According to Zeisler and Christ by William. S. Dorn. The reason that I don't talk about it is because it doesn't strike me as an actual chronology. Dorn just takes the info from one person (Zeisler), uses another (Christ) for small holes in the timeline, and then uses his own logic to date only one story - 'The Adventure of the Three Gables' (3GAB). So, let's examine this knotty problem.
All of the ones I have fall into sub-categories. At least I think they do. Not all are what I'd call "true" chronologies. A true one, to me, is one that tells us the logic and reasoning behind one's findings and is just about chronology. An "extended" one has the logic and reasoning, but is also a clearing-house for all sorts of Canonical problems. An "unrevealed" one doesn't tell us any of the logic at all, just dates. And an "imitation" uses other people's dates entirely, or almost entirely, to create a timeline. This is where I would place Mr. Dorn's book IF it were used in my work.

Now, if I were so inclined I could also come up with subcategories here to make the whole thing even more convoluted, but I won't. I could talk about how Bradley & Sarjeant agree with Baring-Gould most of the time, but often when they don't they like Dakin. I could mention that Keefauver considers Zeisler 'The King of Chronology' and goes along with a lot of his logic, but doesn't always come up with the same dates. I might point out that Christ has a lot of "but's" and "however's" under his chronological findings that show he isn't always convinced of his dates.
I could also make sub-categories based on how the chronologies are made. Whether the stories are solely plotted against each other, or if internal evidence is used, or if both are figured in. Yeah, it could get messier. And the above lists may continue to grow as I do have two more, as you'll recall from my September blog post, that I haven't decided are original works yet or merely imitations. (Hey, a guy gets busy, ya know?)
In order to solve the question of whether they're imitations or not, I'm going to have do some study into chronology comparisons. It's going to take some time, but I don't mind. However, you'll have to wait. The filing and paperwork will take months.
(On a quick side note...my speaking calendar for the coming year seems to be more open than usual. Changes in management at certain gatherings have caused me to be listed as only a back-up. Not that that's a bad thing. So, if you know of a group or gathering that could use a speaker let me know and I'll see what I can do.)
Thanks for reading. See you next month.
