Where is the best place to learn about the p-adic L-functions of Elliptic Curves? Doing a bit of research I have found books like "An Introduction to Cyclotomic Fields" by Washington, but those only seem to discuss the p-adic analogues of Dirichlet L-functions.

As background, I am a student whose main relationship with algebraic Number Theory is Joe Silverman's "The Arithmetic of Elliptic Curves". I have also taken a course on Analytic Number Theory.
