The IIIF playground
Below is a real IIIF viewer with three collection items already loaded. Zoom deeply into any image, page through a manuscript, and drag two windows together to compare them.
What is IIIF? The International Image Interoperability Framework is a shared standard cultural institutions use to publish images and their metadata. Because it's open, one viewer can render material from libraries and museums worldwide — so you can paste a manifest from your own institution and it just works.
