We present a database of the latest stellar models of the $Y^2$ (Yonsei-Yale)collaboration. This database contains the stellar evolutionary tracks from thepre-main-sequence birthline to the helium core flash that were used toconstruct the $Y^2$ isochrones. We also provide a simple interpolation routinethat generates stellar tracks for given sets of parameters (metallicity, mass,and $\alpha$-enhancement).Comment: 7 pages, TeX, 1 eps figure.
