Opinions on 'The Variational Principles of Mechanics' by Cornelius Lanczos

I wouldn't call Lanczos "a textbook". If you just want to pass a course and tick another box on your study schedule, don't waste your time with it. But if you want a book that you can keep re-reading profitably for the next 40 or 50 years, buy it.
