This bibliography lists and abstracts all of the Soviet literature dealing directly with masers and lasers published before 1963. Peripheral articles, articles which serve as partial foundation and general background to the subject, have been omitted. The earliest reference is the doctoral dissertation by V.A. Fabrikant, dated 1939. References are given to a few translations dated 1963, but in all cases the originals were published prior to the end of 1962. (Author).
