We present data fundamental for the study of B-type stars. Interstellar reddening ratios, intrinsic colors, comparison stars, reddening-free indices, and calibrations for MK spectral type, effective temperature, and absolute visual magnitude are given. In particular we discuss briefly the use of 13C photometry for measuring stellar distances and for studying intrinsic excesses of Be and shell stars.
