The introduction of image tubes makes spectroscopic studies in the red and near infrared spectral regions much more efficient. Work currently done at the Lick Observatory by the Los Angeles binary star investigators is reported. Preliminary results on element abundances in the subgiant in U Sagittae indicate that there may indeed exist systematic abundance anomalies of potential relevance to the problem of the solar neutrino flux. Emission at Hα has been observed in many systems, and several types of circumstellar features are indicated. It is suggested that some Be stars and shell stars are interacting binaries. The possibility of observing very deep stellar eclipses is discussed.
