dc.descriptionOur knowledge of the initial conditions and early stages of high mass star formation is very limited. 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 massive stars BEFORE star formation actually begins. By analogy with the Pre-Protostellar Cores (PPCs) studied for low-mass star formation, one might call such regions Pre-Proto-cluster Cores (PPclCs). We will conclude with some speculation about what such cores might look like and possibilities for their detection.
