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 comprehensive bibliographic achievements in the history of medical science. Initiated in the late 19th century under the direction of John Shaw Billings, the project sought to organize and make accessible the vast collection of medical literature housed within the U.S. Army's library. Billings envisioned a work that would provide researchers with immediate access to global medical knowledge, necessitating an exhaustive cataloging of both books and journal articles across decades of series and volumes.

The design of the catalogue was a labor-intensive undertaking that utilized a dictionary-style arrangement, integrating authors and subjects into a single alphabetical sequence. This methodology was innovative for its time, setting a standard for medical librarianship and research efficiency that influenced subsequent information retrieval systems. The series was met with immense academic acclaim upon its release, serving for decades as the definitive reference tool for physicians and medical historians before being eventually superseded by computerized databases like MEDLINE.
