The Henry Draper Catalogue (HD) is an astronomical star catalogue published between 1918 and 1924, giving spectroscopic classifications for 225,300 stars; it was later expanded by the Henry Draper Extension (HDE), published between 1925 and 1936, which gave classifications for 46,850 more stars, and by the Henry Draper Extension Charts (HDEC), published from 1937 to 1949 in the form of charts ...

During the daytime, female assistants like Florence analyzed the resultant spectra by reducing values, computing magnitudes, and cataloging their findings. [17] She is credited with determining the positions and magnitudes of the stars listed in the 1918 edition of the Henry Draper Catalogue, [18] which featured the spectra of roughly 222,000 ...
[9] [10] In response, the HCO began work on the first Henry Draper Catalogue, a long-term project to obtain the optical spectra of as many stars as possible and to index and classify stars by spectra. [11] Fleming was placed in charge of the Draper Catalogue project. [8] A disagreement soon developed regarding classifying the stars. [7]

The tenth major data release, DR10, released in July 2013, [7] provides images, imaging catalogs, spectra, and redshifts via a variety of search interfaces. The raw data (from before being processed into databases of objects) are also available through another Internet server and first experienced as a 'fly-through' via the NASA World Wind program.
