摘要：

Photographic photometry, derived from 364 blue plates of the globular cluster M14 taken from 1932 through 1980, and from 4 plates taken from 1912 to 1918, is presented for 68 variables. Included are magnitudes for 5 Population 11 Cepheids, 1 field Mira variable, 5 red irregular variables, 40 ab-type RR Lyrae stars, 15 c-type, and 2 possible c-type RR Lyrae stars. Light curves are constructed for 21 RR Lyrae variables for which periods and light curves have not been published earlier. Tables summarizing the light curve parameters, period change rates, and colors of the variables are presented.
