A catalog of 819 sources detected in the Einstein IPC Slew Survey of the X-ray sky is presented; 313 of the sources were not previously known as X-ray sources. Typical count rates are 0.1 IPC count s-1^, roughly equivalent to a flux of 3 X 10-12^ ergs cm-2^ s-1^. The sources have positional uncertainties of 1.2' (90% confidence) radius, based on a subset of 452 sources identified with previously known pointlike X-ray sources (i.e. extent less than 3'). Identifications based on a number of existing catalogs of X-ray and optical objects are proposed for 637 of the sources, 78% of the survey, (within a 3' error radius) including 133 identifications of new X-ray sources. A public identification data base for the Slew Survey sources will be maintained at CfA, and contributions to this data base are invited.
