In a continuation of our systematic search for high proper motion stars in the Digitized Sky Survey , we have completed the analysis of northern sky fields at galactic latitudes above 25 degrees .
With the help of our SUPERBLINK software , a powerful automated blink comparator developed by us , we have identified 1146 stars in the magnitude range 8 < r < 20 with proper motions 0.500 < \mu < 2.000 \arcsec 
yr ^ { -1 } .
These include 1080 stars previously listed in Luyten ’ s proper motion catalogs ( LHS , NLTT ) , 9 stars not previously listed in the Luyten catalogs but reported elsewhere in the literature ( including 1 previously reported by our team ) , and 57 new objects reported here for the first time .
This paper includes a list of positions , proper motions , magnitudes , and finder charts for all the new high proper motion stars .
Combined with our previous study of low galactic latitude fields ( see Paper I ) , our survey now covers over 98 % of the northern sky .
We conclude that the Luyten catalogs were \simeq 90 % complete in the northern sky for stars with 0.5 < \mu < 2.0 \arcsec down to magnitude r=19 .
We discuss the incompleteness of the old Luyten proper motion survey , and estimate completeness limits for our new survey .
