Recommend some undergrad textbooks

Hi, i'm about to go into my 3rd year undergrad maths degree and was wondering if you could recommend any good textbooks on classical mechanics (specifically lagrangian and hamiltonian), and quantum mechanics. I'm currently looking at the following:

Mechanics (Landau/Lifschitz)

Introduction to Quantum Mechanics (Griffiths)

Are there any better?

Thanks.

If you are looking for a mathematics text then Arnold's *Mathematical Methods of Classical Mechanics* is excellent and the gold standard is *Foundations of Mechanics* by Abraham and Marsden. These latter two books would normally be considered appropriate for graduate students, usually beyond the first year.

A rather dry, but encyclopedic older book is Whittaker's *A Treatise on the Analytical Dynamics of Particles and Rigid Bodies*.

I'm not sure that there is anything much better than Griffiths book on QM. One old standard is *Quantum Mechanics* by Messiah. It is probably worth taking a look at volume 3 of *The Feynman Lectures on Physics*, to at least get a flavor for Feynman's viewpoint.
