A search for faint blue stars conducted at the Observatories of Tonantzintla and Minnesota has yielded 8746 objects which are somewhat blue. The data file is organized into three sections with the same column format. The first 1569 records are for stars with U-V of -0.4 or bluer, which are very definitely blue (Table II of the paper). The next 2929 stars are somewhat blue, with U-V values of -0.3 or -0.2 (Table III of the paper). The final 4248 records give data for stars with U-V of -0.1 or 0.0 (Table IV of the paper). Photometric, spectroscopic, and proper-motion data have later been acquired for these objects, which revealed the great variety of the objects in this catalogue: white dwarfs, subdwarfs, QSOs (quasars), compact and active galaxies. Finding charts and details about the nature of these blue objects can be found in the following papers: Haro G., and Chavira E.: 1987RMxAA..15..107H ; Chavira E.: 1988RMxAA..16..123C, Chavira E., 1990RMxAA..20...47C, and 1992RMxAA..24..139C
