The next great, widely used star list to appear after the BD was the Henry Draper Catalogue of stellar spectra, compiled by Annie J. Cannon at Harvard from 1911 to 1915 and published from 1918 to 1924. It includes 225,300 stars numbered in simple order of right ascension. More were added later in the Henry Draper Extension; these bear HDE numbers. Any star with an HD or HDE designation is guaranteed to have had its spectrum measured.
