Among field stars recent work includes development of classification notation of the strong-CN stars, and the recognition that the barium star with weak CN (HD 130255) may actually be a dwarf barium star. The now established presence of weak-G-band stars on the AGB of globular clusters suggests that such field stars as HD49500 may be in the AGB stage.

Such progress as has been made in the application of modern detectors to the classification of faint stars in the nuclear bulge of our galaxy, and in the Magellanic Clouds, is summarized.
