Carbon and nitrogen abundances, as well as the strengths of calcium II H and K and the ..delta..v = 0 cyanogen band, have been measured in red giant stars in the globular clusters M3 and M13. The data consist of spectrophotometric scans of low resolution (10 A) of 29 giants in M3 and 35 giants in M13 in the wavelength region 3000--5000 A.
