We present the full spectroscopic white dwarf and hot subdwarf sample from the Sloan Digital Sky Survey (SDSS) first data release, DR1. We find 2551 white dwarf stars of various types, 240 hot subdwarf stars, and an additional 144 objects we have identified as uncertain white dwarf stars. Of the white dwarf stars, 1888 are nonmagnetic DA types and 171 are nonmagnetic DBs. The remaining (492) objects consist of all different types of white dwarf stars: DO, DQ, DC, DH, DZ, hybrid stars such as DAB, etc., and those with nondegenerate companions. We fit the DA and DB spectra with a grid of models to determine the Teff and log g for each object. For all objects, we provide coordinates, proper motions, SDSS photometric magnitudes, and enough information to retrieve the spectrum/image from the SDSS public database. This catalog nearly doubles the known sample of spectroscopically identified white dwarf stars. In the DR1 imaged area of the sky, we increase the known sample of white dwarf stars by a factor of 8.5. We also comment on several particularly interesting objects in this sample.

Spectroscopic analysis of DA white dwarfs with 3D model atmospheres (2013, background): “The spectra, which cover a wavelength range of 3800 to ∼10 000 Å with a resolution of R ∼ 1800, appeared to have some calibration issues up to the DR7 (Kleinman et al. 2004; Eisenstein et al. 2006; TB11; GB11).”
The INT photometric H-alpha survey of the northern galactic plane (2005, background): “It is a reasonable guess that over a thousand will be discovered in IPHAS data, just as have been discovered in a comparable sky area around the north Galactic cap via the Sloan survey (Kleinman et al 2004).”

New white dwarf and subdwarf stars in the Sloan Digital Sky Survey Data Release 12 (2015, methodology): “As an independent check, and to be consistent with the earlier SDSS white catalogues, we also fitted all DA and DB white dwarf spectra and colours with the AUTOFIT code described in Kleinman et al.

White dwarf mass distribution in the SDSS (2006, methodology): “They did not study the potentially highest mass stars with log g > 9, because they were limited by the stellar atmosphere fit by Kleinman et al.
