Learning spectral methods in numerical analysis I'm trying to learn the theory about spectral methods without any specific ties to a particular program like MATLAB. I tried to search for some lecture videos but it seems very limited and I'm not sure which books are well suited for self-learning about this topic.
Does anyone know of any good books and/or lecture videos for learning about this method? 

Numerical Recipes pages 1083-1096 is a good intro (for me, a non-expert).
They further recommend Boyd. Links:
