For his book Baker Street Irregular, recently reviewed on this blog, Jon Lellenberg has created "a rolling weekly feature about the hero's times, settings and troubles -- accessible from my website's Novel page, or directly at http://www.bsiarchivalhistory.org/BSI_Archival_History/Woodys_World.html. The first installment just went up, and future installments will stretch out over the next several months. Comments and suggestions are welcome."
I've had a look at the site, and it's excellent. Check it out.
