Books:

Beware: I am appalled to discover that defective copies of Introduction to Electrodynamics (3rd and 4th editions) and Introduction to Quantum Mechanics (2nd edition), are selling in Europe, under imprints like "Pearson New International Edition." Some covers show a lightning bolt, or a jig-saw puzzle, whole chapters are sometimes missing (or in the wrong order), and the index contains nonsensical entries. There are probably other errors I did not notice. I am pleased that Pearson is putting out lower-priced (paperback) editions for the international market (given that the hardback American editions are so obscenely overpriced), but I cannot understand why they do not simply reprint the correct version verbatim. I suppose the defective copies will be adequate for most users, but I am acutely embarrassed, and I do apologize. If it becomes a problem, I suggest you contact the publisher, and request a clean copy. If that doesn't work, email me and I will send an electronic copy of the missing material.
