Rotational velocities and spectral types have been determined for Be stars in 12 open clusters in both the northern and the southern sky, and color-magnitude or H-R diagrams constructed for each from available photometric data. The location of the Be stars in the color-magnitude diagrams shows again that Be stars may exist in various evolutionary stages, including the essentially unevolved stage. Although many Be stars are considerably off the zero-age main sequence, it does not necessarily follow that these are in the core-contraction stage because circumstellar reddening and rotationally induced gravity darkening of the underlying star will also move stars to the right of the main sequence in a color-magnitude diagram. The evolutionary status of Be stars seems still to be quite uncertain.
