In this study of Taurus-Auriga, we combine pre-main-sequence ages from our own evolutionary tracks with stellar positions from observational surveys. Aided by the extensive millimeter data on the molecular clouds, we develop a picture of the region's history. Description: We base our own investigation on a sample of 153 stars, drawn from a number of sources in the literature. Most are from the compilation of Kenyon & Hartmann (1995, Cat. J/ApJS/101/117), who in turn utilized and supplemented earlier studies in the optical, near-infrared, and X-ray regimes. The membership list of Kenyon & Hartmann is complete to V∼5 mag. Within the L1495E cloud, both Strom & Strom (1994ApJ...424..237S) and Luhman & Rieke (1998ApJ...497..354L) conducted deeper surveys, which doubled the number of known members in this area. Briceno et al. (1998AJ....115.2074B) focused on very low mass objects in both L1495E and other regions, uncovering nine new stars. Both the 2MASS project (Luhman, 2000ApJ...544.1044L) and the large-scale, optical CIDA survey (Briceno et al., 1999AJ....118.1354B) yielded additional objects. Finally, we have added 13 stars from the ROSAT study of Wichmann et al. (2000A&A...359..181W). File Summary:
