Ways to solve a 2D Laplace equation I'm looking for a survey of methods to solve Laplace equation in two dimensions.

Is there a book describing them with hints regarding their applicability for various cases?

I mean analytical methods, not numerics.
Since Community bumped the question, I might as well put something relevant here. My reaction to seeing "two dimensions" and "Laplace equation" in the same sentence is "ooh, I can use conformal maps to do that". The idea is that since the Laplace equation is invariant under conformal maps, we can transform our boundary value problem into a BVP on a nicer domain, a disk or a halfplane. This works very well for the Dirichlet problem; for the Neumann problem the boundary conditions must be multiplied by the derivative of the conformal map, which makes life a bit harder.  


Low-level explanation with lots of examples and pictures. Unfortunately it dates  back to 2003 when MathJax wasn't around. We are spoiled by MathJax now. 
Conformal Mapping: Methods and Applications, Dover book by Roland Schinzinger and Patricio A. A. Laura. From the preview it looks very thorough and accessible. 
Research-level explanation with emphasis on polygonal domains
Here, I am giving you a link. See the file. You will get some hint.
