This page groups constellations by whether each one holds official recognition from the International Astronomical Union. Wikipedia notes that "in 1922, the International Astronomical Union (IAU) formally accepted the modern list of 88 constellations, and in 1928 adopted official constellation boundaries that together cover the entire celestial sphere." Browsing by iau-status lets a visitor tell an officially recognized constellation from an older or unofficial one.
