Positions and spectra of 1665 MHz OH and 23235 MHz H₂O masers in 74 star-forming regions are presented. This supplement provides an electronic version of the complete VLA database of interstellar masers observed by Forster & Caswell (1989A&A...213..339F). The fields observed comprise the majority of known interstellar OH and H₂O maser associations at galactic longitudes observable from both hemispheres. The database will be useful for interpreting continuum and molecular line observations of these regions, for investigations of the relationship between the masers and their local environment, and for temporal and kinematical studies of the masers themselves.
