In the past weeks, I have struggled with finding suitable tables for integral indentities for Beta functions, Chebyshev polynomials and their like.

I would like to ask for online/offline resources and software, which collect tables of special functions and their properties, integral identities, tables of Fourier/Laplace transforms of special functions, and so forth.

An example is the Bateman Manuscript Project, from which 3 out of 5 books are freely available: http://en.wikipedia.org/wiki/Bateman_Manuscript_Project

Btw, is there way to search effectively for an integral identity?
