We have conducted a systematic search for high proper motion stars in theDigitized Sky Survey, in the area of the sky north of -2.8 degrees indeclination and within 25 degrees of the galactic plane. Using the SUPERBLINKsoftware, a powerful automated blink comparator developed by us, we haveidentified 601 stars in the magnitude range 9<r<20 with proper motions in therange 0.5 to 2.0 arcsec/yr which have not been observed with the HIPPARCOSsatellite. Among those, we recovered 460 stars previously listed in Luyten'sproper motion catalogs (LHS, NLTT), and discovered 141 new high proper motionstars, ranging in magnitude from R=13.0 to R=19.8. Only 9 stars from the Luytencatalogs that were not observed by HIPPARCOS could not be recovered withSUPERBLINK: 3 had proper motions larger than the search limit of the code(>2.0\arcsec/yr), and 5 were missed because they were either too bright forSUPERBLINK to handle or they are in the immediate proximity of very brightstars. Only one of Luyten's stars (LHS1657) could not be recovered at all, evenby visual inspection of the POSS plates, and is now suspected to be bogus. Thevery high success rate in the recovery by SUPERBLINK of faint Luyten starssuggests that our new survey of high proper motion stars is at least 99 percentcomplete for stars with proper motions 0.5 to 2.0 arcsec/yr down to R=19. Thispaper includes a list of positions, proper motions, magnitudes, and findercharts for all the new high proper motion stars.Comment: 24 pages, 16 figures.
