Chess Automatons by Sarah Beth
First, I want to acknowledge Chess.com member, gretagarbo, for all the help rendered to me, especially in researching Ajeeb. I would go as so far as to say I would have had very little new information on Ajeeb without that help.
Second, I'd like to draw everyone's attention to Jane Irwin's "Clockwork Game," a webcomic, or as she terms it, a docudrama, based (with uncanny accuracy) on the Turk. If you enjoy reading about this pseudo-automaton, visit Jane's pages. I promise, you won't regret it.
Below I've linked all my articles (some may not yet be available).
Books I couldn't find:

Observations upon the automaton chess player of von Kempelen, and upon other automata and androides, now exhibiting in the United States, by Mr. Maelzel: ... upon the chess-board, by the knight's move
