From a NLM Announcement:
The History of Medicine Division (HMD) of the National Library of Medicine (NLM) [recently launched] a new user interface for its premier database, IndexCat, along with the addition of two new collections involving medieval scientific English and Latin texts.
Utilizing software developed by Ex Libris, the new IndexCat interface offers improved viewing capabilities and new layouts for search results and record displays. IndexCat is available free of charge.
Providing access to the digitized version of the printed, 61-volume Index-Catalogue of the Library of the Surgeon General’s Office, IndexCat contains over 4.5 million references to over 3.7 million bibliographic items dating from over five centuries and covering subjects of the basic sciences, scientific research, civilian and military medicine, public health, and hospital administration. Language coverage is international with citations in European and Slavic languages, Greek script, and Romanized Chinese and Japanese titles – some with English translations. A wide range of materials can be discovered through IndexCat, including books, journal articles, dissertations, pamphlets, reports, newspaper clippings, case studies, obituary notices, letters, portraits, as well as rare books and manuscripts.
