Advanced E&M Book Recommendations

[SUDOnym]

could any1 recommend a good E&M book that might be worth reading after having just finished Griffith's book on the subject... so probably a book a little more advanced than Griffith's

 

[fluidistic]

Jackson's Classical Electrodynamics.

I agree with fluidistic's suggestion, but if Jackson seems to difficult, you can try Electromagnetic Fields by Wangsness. It's an undergraduate textbook like Griffiths, but the presentation is more rigorous.
