The distribution of rotational velocities among young stars may provide insight into initial conditions in star-forming regions (e.g. Wolff, Strom, & Hillenbrand 2004). In this contribution, we report projected rotational velocities (vsini) for a large sample of stars drawn from 7 clusters ranging in age from 1--20 Myr (IC 1805, Cyg OB2, NGC 2244, NGC 6611, NGC 6823, NGC 7235, NGC 7380). These data provide the basis for assessing (a) the cosmic dispersion in the distribution of vsini values, N(vsini), for late-O and early- B stars among clusters of similar age; and (b) evolution-driven changes in N(vsini) via comparison of young and ``old'' clusters in our sample.
