Partial Differential Equations for Scientists and Engineers (Dover Books on Advanced Mathematics)

Rating:
Summary: Very Good
Review: Unbeatable as far as breadth. Covers a lot of ground, conceptually it's extremely well organized, and the explanations are very easy to follow. This text is ideal for self-study.

The two major shortcomings are (1) slight lack of depth and (2) the exercises, which are far too few and far too simple.
