I'm currently doing some research about drawing, since that is one of the most important steps in the doll making process. In the course of my search, I ran across a couple of books about modeling for sculpture. I found these at The Internet Archive.
Modelling and Sculpture. Albert Toft. 1911.
Biographical information about Albert Toft is available here:
Modelling: a guide for teachers and students. Edouard Lanteri. 1902.
A biography of Edouard Lanteri can be seen here:
Both of these books are about figurative sculpture, and are available for free download in PDF and other formats. They can also be read online. The book format choices are over on the left sidebar.
