I just noticed that Abramowitz & Stegun's Handbook of Mathematical Functions is available online in its entirety. For anyone not familiar with this tome, it's a compendium of both common (e.g. trigonometric) and esoteric (e.g. Weirstrass elliptic) functions, identities, series expansions, tables, etc. I've had my paperback copy for more than 30 years and still refer to it.
The online version is scanned from a paper copy. Though perhaps less useful than a text version would have been, even a text version would have to have included most of the mathematical formulae as graphic images anyway, so not that much is lost. Nonetheless, if you have a frequent need for this kind of information, the printed version is extremely handy and, at $24.39, a bargain for its jam-packed 1046 pages.
