We will review recent surveys of regions in the early stages of massive star formation using molecular tracers of high density and dust continuum emission and consider the status of evolutionary schemes. Comparison to the situation for low mass, relatively isolated star formation will be used to illustrate the outstanding issues in massive star formation. The problem of initial conditions is particularly acute because there is a lack of observational evidence for regions capable of forming mas","authors_text":"Claudia Knez (Department of Astronomy, Kaisa E.
