That's an excellent question! I, too, would like to have such a reference
available. The last I heard -- and this goes back a dozen years when I first
worked with ARC/Info -- is that the algorithms are rather closely held by
those (like Jack Dagerman) who developed them. After all, the
point-in-polygon and similar problems are why ESRI is able to charge the
extremely high prices they do. It's also the reason why there are more
raster-based analytical GISes than vector-based analytical offerings.
Please let me know what you find out. Have you posted to GIS-L?
