The Index-Catalogue of the Library of the Surgeon General's Office is now searchable. IndexCat, as it is called, provides citation information for monographs and journal articles on
medical topics published between 1892-1961. For locating historical articles, this is an unparalled resource. This is a pilot release so you may experience some connection problems at first. IndexCat provides a link to send comments or questions for improvement.
On an historical note: the National Library of Medicine (NLM) began as a few books in the office of the Surgeon General in 1818. In 1840 a small notebook entitled " A Catalogue of the Books in the Library of the Surgeon General's Office, Washington City, 1840" was drawn up. This is the earliest known catalog of this Library. In 1880, the Index Catalogue described above began publication. It is the precursor to today's NLM Catalog (electronic version known as LocatorPlus).
