Here are some maps of the constellations from the IAU.

They also provide information on other things.

"Which constellation has the most stars fairly easy to see with the unaided eye? The practical answer for observers at mid-northern latitudes would be rich Orion and Taurus, which both have 60 stars brighter than magnitude 5.25. But suppose we were far enough south to see certain constellations high above the horizon, so that they weren’t significantly dimmed by atmospheric extinction. Which constellation would have the most stars brighter than our limit? The answer is Centaurus, with 79. But none of Centaurus is above our map’s horizon now. Neither is Cygnus, tied for second in the ranking with 70 stars." S&T March 2012 page 42.
