During their birth all stars undergo periods of copious mass loss, frequently
characterized by the occurrence of bipolar outflows. These outflows are
believed to play a fundamental role in the star formation process. However the
exact outflow generating method is obscure at present. To elucidate this
problem we are investigating whether the flow properties are correlated over
the entire protostellar mass spectrum. Progress in this area requires that we
assemble a statistically valid sample of high-mass outflow systems. This is
necessary since existing catalogues of such objects are heterogeneous and
statistically incomplete.Comment: 2 pages, 1 figure, uses newpasp.sty. To appear in "Hot Star Workshop
