Bart Bok speculated back in the 1940's that dark cloud cores (i.e. Bok globules) are sites of star formation. The means for probing the dark cloud cores, molecules, were not discovered until much later. Today, we can finally say Bart Bok was right! Evidence for collapse in dark cloud cores will be discussed in general, along with specific examples of collapse candidates. We also describe methods to search for new candidates and the complications in identifying the infall motion.
