Griffiths is widely recommended as a solid introductory textbook for quantum mechanics (QM), praised for its numerous exercises. After grasping the basics, transitioning to more advanced texts like Cohen-Tannoudji and Sakurai is suggested, although these are considered graduate-level. Feynman's lectures are noted for their clarity, particularly volume III, while Bransden & Joachain's "Intro to QM" is also recommended. Schiff's 1947 edition is seen as elementary, and Blokhintsev's book is mentioned as a good introductory resource. Concerns were raised about Gasiorowicz's book, which some reviews criticize for not effectively connecting concepts, prompting discussions about alternatives like Shankar, who provides a comprehensive mathematical introduction, and Liboff. Overall, Griffiths and Shankar are viewed as reliable options for those new to QM, despite some critiques of Griffiths' notation and pacing.
