The SAO catalogue contains this major piece of information not in Draper, the proper motion of the stars, so it is often used when that fact is of importance.
His most important work was on the analysis of the proper motion of 3,136 stars from James Bradley's catalog, which was the first usable method to deduce the rotation
Lowell Proper Motion Survey, Lowell Observatory Bulletin,
Edmond Halley published the first measurements of the proper motion of a pair of nearby"fixed" stars,
Proper motion was suspected by early astronomers(according to Macrobius,
the time series for the Sun does not reflect its proper motion and will be excluded.
He hoped to set a basis for future studies of the proper motion of nebulae; this turned out to be more or less in vain, since distant nebulae will not show any proper motion.
Because the selection biases of the resulting high proper motion samples are well understood
the secular variation, the proper motion, the weighted average absolute parallax
They include a determination of the rate of change of the axial inclination of the Earth and the proper motion of Arcturus, both close to the modern values, whose combination of visual magnitude and large proper motion led Hornsby to argue(incorrectly)
nutation and proper motion.
Stars with large proper motions tend to be nearby;
It's really interesting that Gaia obtained the proper motions of these stars.
A common way of detecting nearby stars is to look for relatively high proper motions.
Added showing a proper motions for some stars.

parallaxes, and proper motions of 118,218 stars were determined with an unprecedented degree of accuracy.
He published multiple papers on stellar absolute magnitudes, proper motions, and radial velocities of various stars,
The catalogue detailed each star's coordinates, proper motions, photometric data,
