PLATE XXXI X The cluster NGC 6868, Messier 71, long thoughl to be a galactic cluster, bul now considered in the globular category. The photograph is from a plate with one hour exposure by D.K. Nbrris with tin- 74-inch David Dunlap reflector, June 21, 1947. Scale, 1 mm =1 \ '.7.
A BIBLIOGRAPHY OF INDIVIDUAL GLOBULAR CLUSTERS By Helen B. Sawyer (With Plate XXXII) Advertisement.—Whoever attempts the enlargement of the bounds of knowledge in any particular branch of science, in justice to himself, the public, and previous laborers in the same field, should make himself familiar with all that has been previously published on the subject. But information of this kind is so widely dispersed through the journals and transactions of learned societies of all parts of the civilized world, that index catalogues or references to authorities are of the utmost importance to the investigator. Smithsonian Institute, Washington, 1877. I. Purpose and Development of Work — Joseph Henry, Secretary, In this bibliography an attempt is made to list under the cluster concerned, all research papers containing information on individual globular clusters. The purpose is to enable any astronomer to find out what work has been done on a specific cluster, thus saving time and avoiding duplication of research. Globular clusters, with a large range in linear diameter, absolute magnitude, and numbers of variable stars are being treated more and more as individual systems. Only clusters thought to belong directly to our own galaxy are included, and only clusters considered globular at present. A few minutes of studying the bibliography will show the type of information available on the cluster. A few hours of reading the original sources indicated in this work will give the reader all the published facts about the object. For only a few clusters, notably Messier 13 in Hercules and Messier 3 in Canes Venatici, is the literature volumi- nous and unwieldy. For over twenty years I have maintained a card catalogue of references to globular cluster literature. This catalogue is a necessary complement to the 2000 globular cluster photographs which have now been accumulated at the David Dun lap Observatory on about one-half of the known globular clusters. One result of this catalogue was the publication by the writer in 1939 of A Catalogue of 1116 Variable Stars in (lobular Clusters (Dunlap Publication, 383
