I'm not sure there's such a thing as a book or place with _all_ the
alternate fingerings, but the Woodwind Fingering Guide
http://www.sneezy.org/wfg/ has many.

An excellent source of trill fingerings are the Rubank Advanced Method
Books. A trill chart is bound in at about the center and it is laid out
showing both notes of the trill and one or more ways to execute that trill.
The advantage over a regular fingering chart is that you don't have to look
up each fingering individually and then experiment with the combinations.
And regular charts may not give something useful for certain awkward trills
such as clarion Ab to Bb.
