Introduction to Electrodynamics is probably the best book I have read on Electrodynamics at the Introductory level, though I have heard great reviews on the Classical Electrodynamics by Jackson which is what I am planning to read very soon. This book presents the subject matter in a very informal way which is what Griffiths is successful on explaining the boring subject at times in an articulate way. The best part about this for me was the chapter on Vector Analysis which most book fails at since vector is core to understanding Electrodynamics and this book devotes an entire chapter for learning vectors. If you are planning to study just the basic part of Electrodynamics, then you can study up to chapter 6-Magnetic Fields in Matter and skip the remaining Chapters, but I suggest you to study the remaining chapters as well. The problems in the book are average ones, not so hard and not so easy, so if you give some time to yourself, you can easily solve them. I bought the International edition of this book and I am happy with the Quality of the pages and book. The one thing that I don't like about this book is its solutions to problems which is the another book which I think was hastily and poorly written and don't do justice to this book. The one book which might give a tough competition to this book is Electricity and Magnetism by purcell. Nonetheless, a great book for all the Electrodynamics fans.
