"The Medical Heritage Library (MHL), a digital curation collaborative among some of the world’s leading medical libraries, promotes free and open access to quality historical resources in medicine. Our goal is to provide the means by which readers and scholars across a multitude of disciplines can examine the interrelated nature of medicine and society, both to inform contemporary medicine and strengthen understanding of the world in which we live. The MHL’s growing collection of digitized medical rare books, pamphlets, journals, and films number in the tens of thousands, with representative works from each of the past six centuries, all of which are available here through the Internet Archive."

In March 2018 this library contained over 239,000 items.

From the Wikipedia, (partial) accessed 12-2016:

The MHL began digitization of monographs in 2010 with an initial grant from the Sloan Foundation. Work on the MHL project has continued with funding support from collaborating institutions, the National Endowment for the Humanities , and the Mellon Foundation via a program administered by the Council on Library and Information Resources. All digitized works are located at the Internet Archive.

The collection includes books, pamphlets, journals, and video and audio recordings in the history of medicine and related fields. A working list of subject headings is available here. Titles have been chosen for their scholarly, educational, and research value. The MHL consults with a volunteer group of scholars in the history of medicine and related fields and surveys its users regularly. As of August 2014, the collection consists of nearly 60,000 items including monographs, journals, audio and video....

The MHL has created a full-text search tool for use by researchers.^[1] The tool allows users to search the full-text of one or more items simultaneously. The tool is in an extended beta release and comments or questions are welcome!

The UK Medical Heritage Library started in 2014 with nine digitisation partners in England and Scotland, including [UCL] (University College London), the [University of Leeds], the [University of Glasgow], the [London School of Hygiene & Tropical Medicine], [King's College London], and the [University of Bristol] - along with the libraries of the [Royal College of Physicians of London], the [Royal College of Physicians of Edinburgh], and the [Royal College of Surgeons of England]. The original partnership is between the [Wellcome Library] and [Jisc]. Material digitized by the UK MHL project is also available through the MHL portal at the Internet Archive and searchable through the full-text search tool described above.
