About Harvard IIIF

Two APIs: One for image retrieval, one for image display.

The International Image Interoperability Framework (IIIF) defines universal standards for describing and delivering images over the web.

These standards are the result of collaborative efforts across universities, museums, libraries, and other cultural heritage institutions around the world.
