One approach to learning about stellar populations is to study them at three different levels of resolution. First in our own galaxy; secondly from nearby galaxies where stars can still be resolved; and thirdly in remote galaxies in which the stellar population can only be studied in integrated light. This International Astronomical Union Symposium covered the range of galaxies in its study of their stellar populations. Interspersed with theoretical papers, the observational papers provide a presentation of the progress that has been made in the field.
