Janus Books, Ltd. which sells fine and first editions of Sherlockiana and other detective fiction, is NOT related in any way to the Janus Books Publishing Company which produced textbooks and was located in California.

That company was bought out by Simon and Schuster in the early 1990s and ceased publishing under its own name. According to someone who worked for them, many of that company's books are still available under the Globe-Fearon imprint which is owned by the Pearson Learning Group.
