The galaxies of the Local Group can serve as useful laboratories for understanding the formation and evolution of massive stars. We are nearing completion of a 3-year survey to image many of nearby star-forming galaxies using the CTIO and KPNO 4-m telescopes. Images are obtained in broad-band UBVRI as well as 50A wide interference filters centered on Hα , [OIII], and [SII]. Calibration of the broad-band data is being carried out with the Lowell Observatory 1.2-m Hall telescope. We have obtained images of the following systems: M31 (10 fields), M33 (3 fields), NGC 6822, IC 10, Phoenix, WLM, Sextans A, and Sextans B. Poor weather this Fall prevented us from completing our data on Pegasus and IC1613, but we're hoping to obtain these data next year. We have refined the IRAF pipeline for reducing these data, and developed many scripts for the daunting photometry task, which we have made available on our web site, ``http://www.lowell.edu/ massey/lgsurvey". Our images were among the first in the fledgling NOAO Science Archive, and as of this meeting we will have released all of the images for the galaxies with complete data, an dwe are hard at work on the photometry. In this talk we will show many pretty pictures, and outline our procedure for actually getting science out of our data. This work has been partially supported by the National Science Foundation through grant AST-0093060.
