I know the Los Angeles CA library system offers both Ancestry and Heritage Quest. I just checked from home, and I can access Heritage from home (great! because the printer at my branch library is very tricky!), though not Ancestry. Fortunately for me, the Southern CA Genealogy Society has a full membership to the latter (as well as Heritage), so I can access and print Ancestry census records over there - only abt 13 miles away.
