Can anyone point me to a website or book that describes the lanczos interpolation algorithm in reasonably understandable, but still mathematical terms?

Don't know about a website, but I have a copy of his "applied analysis"


There are some intresting observations on how to make a Fourier transform converge faster. Can't recall anything about interpolations, but wolfram gives a referemce..
