Animation edit

Can anyone find more decent sources about Booth's animation work? There's many books with assumptions that films were animated, but when watching Artistic creation and The hand of the artist it is obvious that there's no animation in those. I think The ? Motorist (1906) by Booth may include some early stop motion (I'm not sure yet) and according to IMdB this was released before The hand of the artist (1907). The 1910 or 1911 remake "The automatic motorist" is more convincing and he zeppelins in "The Airship Destroyer" (1909) look like a nice example of some type of mechanical animation (painted on sliding glass plates?). Any references of some authority that describe these as animation would be welcome.
