The present report is drastically shorter and, therefore, different in form from previous reports. While galactic research has increased considerably in recent years, the financial situation in the IAU made it necessary to reduce the size of the reports to half their previous size. This obliged us to adopt an almost telegraphic style in our report. However, an extended version of the report, including also the necessary references, will be published by the University of Thessaloniki and distributed to members of Commission 33. Any other interested astronomer may write to ask for a copy.

The report has been prepared by G. Contopoulos (Sections I, V, VI) and S. McCuskey (Sections II, III, IV). In our work we have been helped by Drs Kerr (radio astronomy) and Haradze (Russian contributions). Dr Elvius has written the Report of the Committee “Selected Areas”. We could cover the literature up to the fall of 1969, plus work in progress, reported by members of our commission.
