From the National Library of Medicine:
NLM is pleased to announce an Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) service for its Images from the History of Medicine (IHM) database, which provides access to over 70,000 images from the NLM’s world-renowned historical prints and photographs collection that illustrates the social and historical aspects of medicine from the Middle Ages to the present.
The new service provides access to the metadata of all items in IHM, opening this database to new uses and new users, and enhancing interoperability with other institutions. OAI-PMH is a standard developed by the Open Archives Initiative for harvesting metadata from digital resources.
IHM via OAI-PMH joins two other NLM OAI-PMH services that provide access to biomedical information of the NLM, for Profiles in Science, an extensive digital project of the Library that provides online access to archival collections of twentieth-century leaders in science, medicine, and public health, and for the life sciences repository PubMed Central (PMC), which currently contains 3.3 million articles from medical journals dating from the early nineteenth century to the present.
