Fully Featured IIIF Viewer

Mirador is a configurable, extensible, and easy-to-integrate image viewer, which enables image annotation and comparison of images from repositories dispersed around the world. Mirador has been optimized to display resources from repositories that support the International Image Interoperability Framework (IIIF) API's. It provides a tiling windowed environment for comparing multiple image-based resources, synchronized structural and visual navigation of content using OpenSeadragon, Open Annotation compliant annotation creation and viewing on deep-zoomable canvases, metadata display, book reading, bookmarking and more.

Full Featured

Mirador implements the full client functionality of the IIIF Image and Presentation APIs. It provides tools for bringing in metadata, images, structures, and can create, edit, delete, and view annotations in Open Annotation Format.


Mirador can be easily configured to provide the simple functionality of an embedded viewer or bookreader, or opened up into a fully-featured scholarly workspace.

Development of Mirador has been generously funded by a grant from the Andrew W. Mellon Foundation. It has been a collaborative and global effort from the start, involving significant efforts from talented professionals from across the world.

The lead development team consists of Drew Winget from Stanford University and Rashmi Singhal from Harvard University. Their expert work and partnership has been a shining example of effective interinstitutional collaboration.

Special thanks to Rashmi’s Harvard colleagues: Jeff Emanuel, Chip Goines, Professor Jeffrey Hamburger, Jud Harward, Dave Mayo and Randy Stern.

At Stanford, Drew’s Mirador 2.0 work was helped immensely by Ben Albritton, Gary Geisler, John Haeger, Christopher Jesudurai, Michael Keller, Jack Reed, Robert Sanderson, Stuart Snydman, Jennifer Vine and Bridget Whearty. Note that much of Mirador 2.0 was based the 1.0 version, and especially Christopher Jesudurai’s work on the initial effort as lead developer.

Significant contributions to development, testing and technical advice have come from colleagues on the Mirador Technical Advisory Group. Special thanks to Mike Appleby, Tom Crane, Shaun Ellis, Bryan Haberberger, Paul Jones, Sean Martin, Matthew McGrattan, Mark Patton, Regis Robineau, Rafael Schwemmer, Ed Silverton, William Straub, Jon Stroop, Ken Tsang and Charles Zeng.

The Mirador team would also like to acknowledge the contributions of Ian Gilman, the maintainer of OpenSeadragon. Not only is OpenSeadragon the core image viewing technology used by Mirador, but Ian made important enhancements to OpenSeadragon to support the IIIF specifications and other specialized functionality.

Mirador 2.0 has been a gratifying 16-month long collaboration. We are excited to expand the community of contributors in the next and future releases.
