In the review, I attempt to focus on what we have recently learned from the observations about three general topics of great theoretical interest:

  1. 1. evidence for evolution of white dwarf surface abundances,

  2. 2. the special problems of determining atmospheric parameters and abundances at the cool end of the sequence, and

  3. 3. evidence for a peaking of the white dwarf luminosity function at Mbol = + 15 ± 1, with possible implications for cooling theory and the history of galactic star formation.
