Index-catalogue of the Library of the Surgeon General's Office, United States: Authors and Subjects

The Index-catalogue of the Library of the Surgeon General's Office stands as one of the most monumental bibliographical achievements in medical history. Conceived in the late 19th century under the direction of John Shaw Billings, the project was intended to make the vast, disorganized medical holdings of the United States Army Medical Museum accessible to physicians and researchers. Billings envisioned a comprehensive system that combined author and subject entries in a single alphabetical sequence, a task that demanded immense organizational rigor and became the backbone of modern medical information retrieval.

The design and compilation were driven by the meticulous standards set by Billings and his collaborator, Robert Fletcher. They drew upon the evolving principles of library science to categorize millions of journal articles and monographs, effectively creating a precursor to the digital databases used by the National Library of Medicine today. Upon its publication, the series was received with international acclaim for its scholarly depth, becoming an indispensable reference tool that defined medical research practices for generations of practitioners and historians.
