The review papers in this volume provide an in-depth examination of complex astrophysical phenomena of star formation via multi-wavelength observations and modeling. Among the fundamental issues discussed in the book are:

The role of gravity and magnetized turbulence in the formation and evolution of molecular clouds
The stellar feedback (supernovae, HII regions, winds, cosmic rays) in regulating star formation
The origin of the stellar initial mass function and its universality across various environments
Jets, magnetic fields and high energy particles in stellar clusters
The origin of the first stars and black holes

The goal of these papers is to review the major processes governing star formation and to investigate how they are interlinked. In doing so, they provide an in-depth look at the tremendous theoretical and observational progress that has been made in the recent past and also outline future perspectives.
