However, the version of Stanislavski's practice these students took to the US with them was that developed in the 1910s, rather than the more fully elaborated version of the "system" detailed in Stanislavski's acting manuals from the 1930s, "An Actor's Work" and "An Actor's Work on a Role". The first half of "An Actor's Work", which treated the psychological elements of training, was published in a heavily abridged and misleadingly translated version in the US as "An Actor Prepares" in 1936. English-language readers often confused the first volume on psychological processes with the "system" as a whole. Many of the American practitioners who came to be identified with the Method were taught by Boleslawski and Ouspenskaya at the American Laboratory Theatre. The approaches to acting subsequently developed by their students—including Lee Strasberg, Stella Adler, and Sanford Meisner—are often confused with Stanislavski's "system".
