OCLC
OCLC is a nonprofit global library cooperative that provides shared technology services, original research, and community programs. Through OCLC, member libraries produce and maintain WorldCat, the most comprehensive global network of data about library collections. With CONTENTdm, libraries are able to build, showcase, and preserve digital collections. Its modern, responsive interface is easy to customize and allows patrons to explore collections on any device. CONTENTdm integrates with the IIIF image and presentation APIs, allowing users to share images across collections and connect your collections with many tools and viewers. With the CONTENTdm API you can develop custom interfaces by integrating your collections with maps or online shopping carts.
