Abstract: Stellar rotation periods measured in open clusters have proved to be extremely useful for studying stars' angular momentum content and rotationally driven magnetic activity, which are both age- and mass-dependent processes. While period measurements have been obtained for hundreds of solar-mass members of the Pleiades, period measurements exist for only a few low-mass ($<br />Comment: Accepted for publication in the Astrophysical Journal; 27 pages, 24 figures, 5 tables
