Scientific paper

We discuss the observational definition of blue stragglers and present a catalog of 58 blue-straggler candidates in six open clusters (NGC 752, 2360, 2420, 2682, 6939, and 7789) chosen to cover the range of ages from 1.6 to 5 Gyr. Candidates which are nonmembers based on proper motions are not included in the catalog. New radial-velocity observations are used to identify additional candidates which are nonmembers. We find that the blue-straggler samples in 6939 and 7789 are significantly contaminated by nonmembers.
