Excerpt from Ophthalmic Literature, Vol. 4: March, 1914There are many directions in which cooperation is essential to efficiency, but in none is it more necessary than in the mastery of the current literature. More than thirty years ago the writer started, for his own use, an index of the literature of ophthalmology. It covered between twenty and thirty periodical publications, stimulated system atic reading, the selection of the important facts or views of the papers read, and it is still used occasionally to locate an article or abstract that is not to be found in the index catalogue of the Surgeon General's Library. After this index was kept up for a few years, it was discovered that a colleague was making an index of the same character, covering the same ground. This at once suggested the use lessness of duplicating the work. If we could cooperate we could cover double the number of journals, and so almost double the value of the resulting index. Shortly after this the Index Medicus became available, and although this did not furnish all that one could desire, it was so far superior to anything possible to an individual reader that the private index was soon discontinued.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
