[PDF] Quantum Physics, Third Edition Stephen Gasiorowicz

First, in defense of the text, there is a focus on the physically interesting material, while extraneous mathematical stuff has been skipped. However, the text is too hard for an introduction, but skips too much material to be a comprehensive guide. Perhaps as the second or third quantum mechanics book on your shelf, this book will do, but not as the first. For the mathematically inclined look to Sakurai (Modern Quantum Mechanics (Revised Edition)). For a very readable if non-standard approach see Feynman (volume 3 of The Feynman Lectures on Physics (3 volume set) (Set v)). Or, for a lighter intro see Griffiths (Introduction to Electrodynamics (3rd Edition)).
