Mirador is an open-source, JavaScript-based tool for comparing and annotating images from multiple repositories. It allows users to view objects side by side without institutional barriers and collect annotations about several objects in one place. Mirador is compatible with the IIIF image and presentation APIs and various IIIF-compliant software. It has been developed since 2013 in a collaborative effort between several universities and is available on GitHub under an open source license.

7. Interoperability and
comparison
• My research concerns the content; I do not
want to be burdened by institutional barriers.
• I want to view objects from multiple
institutions side by side, without significant
friction.
• I want to collect annotations about several
objects in one place.
• I want to be able to refer others to exactly the
thing I am discussing or researching.
