Just to clarify, do you mean you want to know methods regarding SEM in general? If so, the book by Loehlin can be a good start:

Loehlin, J. C. (2004). Latent variable models: An introduction to factor, path, and structural equation analysis (4th ed.). Mahwah, NJ: Lawrence Erlbaum.

A more technical one could be Bollen (1989):

Bollen, K. A. (1989). Structural equations with latent variables. NY: Wiley.
