The Mirador development team at Stanford is happy to announce the release of Mirador v3.0.0. This release represents the first major release of the Mirador software since January 2019. Mirador 3 offers a fresh new redesigned interface and API while keeping many of the well-loved comparison features that Mirador has been known for.

Notable new features in Mirador 3 includes:

  • Two distinct types of workspaces
  • IIIF Presentation v2 and v3 support including Audio/Video resources
  • Rich set of out-of-the-box configurations
  • Themable with included light and dark themes
  • Internationalized and available in 12 languages
  • Designed and built with an accessibility focus
  • Reduction in overall size by 60%
  • Robust plugin framework enables additional customization
  • Annotation creation support for W3C Web Annotations available in a plugin
  • Plugins ready and available for use: image tools, download, share, and annotations

The release notes for this version can be found here: https://github.com/ProjectMirador/mirador/releases/tag/v3.0.0.

Mirador is the digital viewer used in platforms across the Stanford Libraries. It is the image viewer used for content from the Stanford Digital Repository and is viewable in SearchWorks, Spotlight at Stanford, and Purl. Mirador is also used in Stanford Libraries affiliated projects like the Digital Library of the Middle East. While this release represents the final v3.0.0 product, we have had this software in production within Stanford Libraries for over a year to test and make sure it was ready for wider adoption.

Mirador is a global community project, but current and past Stanford Libraries staff have contributed significantly to the success of Mirador 3. Many thanks to the following: 

  • Chris Beer
  • Gary Geisler
  • Jessie Keck
  • Mark Matienzo
  • Jack Reed
  • Stu Snydman
  • Camille Villa
  • Jennifer Vine
  • Drew Winget

Thank you also to everyone who has provided use cases, bug reports, translations, analysis, and features to make Mirador 3 what it is today. This project would not be possible without such a broad contributor base.

A special thanks to our Mirador 3 alpha development partners: University of Leipzig, Princeton University, Bavarian State Library, and Harvard University.

Another noteworthy thank you to the University of Leipzig who also contributed an accessibility audit and report for the project completed by dzb lesen (the German Center for Barrier-free Reading).

And finally, thank you to the University of Minnesota’s “Building a Digital Portal for Exploring Bernard and Picart’s Religious Ceremonies and Customs of All the Peoples of the World” project team, and the Digital Libraries Services and Usability Lab at the University of Minnesota, for help organizing and conducting a usability study for Mirador 3. The usability study was funded by a National Endowment for the Humanities Office of Digital Humanities - Digital Humanities Advancement Grant.


If you are new to Mirador, you can connect to the community on our bi-weekly community calls. Feel free to also reach out on the #mirador channel in the IIIF Slack or our Google Group. We look forward to meeting you.
