The Harvard Library Viewer is a new image viewing platform based on the open source Mirador project and compatible with the IIIF (International Image Interoperability Framework) standard. Harvard Library Viewer provides access to book-like digital objects (manuscripts, broadsides, photograph albums, musical scores, etc.) hosted by the Harvard Library Digital Repository Service (DRS) or any other repository that is IIIF-compatible. Eventually the plan is that this Viewer will replace the Library's current Page Delivery Service (PDS).

Tip: Use * as a wildcard. Examples: cat*, oper* and Harv*

Viewing multiple image objects

You can use the Viewer workspace to compare multiple image objects. This can include image objects at Harvard or external sources, as long as they come from a IIIF-compatible repository. At this time, page-turned objects stored in DRS and delivered by the Harvard Library Page Delivery Service (PDS) are IIIF-compatible. 

In this release of the Viewer, compatible image objects can be loaded directly into the viewer if you know the object’s manifest url. This url retrieves a manifest – a collection of presentation and structural metadata that the Viewer uses to display the object.  (A future release will let you search for compatible image objects.)
