You can't possibly get more for your money than this book. Don't let the price fool you - this is a well written book on electromagnetics.

Most EM texts out there are overpriced and underwritten. They use color drawings and shiny, glossy pages to make up for lack of content. Shadowitz's book is the exact opposite: it's a dover edition, which means it's cheap and doesn't look as good. But this is one of those cases in which you shouldn't judge a book by its cover.
Shadowitz is everything a serious student would like: it covers 1st/2nd year electromagnetism with great detail. It covers many topics, from basic electrostatics and vector analysis, to radiation theory and special relativity. The explanations are always kept clear. A physical context is always provided. Many solved examples are scattered throughout the text. The problems are instructive and odd-numbered ones have solutions at the end of the book. I simply cannot feel sorry that not all books are as good as this one. Although with most Dover books you get what you pay for (which isn't much), this book is an exception. Even if you're studying advanced EM and are using, say, Jackson's text, Shadowitz's text makes a great companion.
I have a few minor quibbles with the book, mainly its use of SI units, but Shadowitz provides appendices which explain how to convert between the various systems.

I am a graduate student in Physics and have found this to be a wonderful reference manual to the "Jackson" graduate text. Shadowitz offers great explanations for sometimes complicated mathematical terms. Additionally, he gives valuable, indepth examples for tensors and makes no illogical or complicated jumps in his derivations of other mathematical formulae.
