The present volume on stellar formation discusses basic physical principles relevant to such processes, regions of recent star formation, galaxy formation and evolution, and the history of star formation in galaxies. Also discussed are OB associations and superassociations, triggered star formations, violent star formation in merging galaxies, and

Six CCD frames for two fields in the area of the rich, presumably old, and unstudied open cluster IC 1311 have been obtained in the BVR bands. The photometric analysis leads to an estimated age of between 1 Gyr (standard models) and 2 Gyr (overshooting models), placing the cluster at a distance of about 4.8 kpc from the sun. Comparison of the
