The IIIF Mirador Viewer developed by the International Image Interoperability Framework (IIIF) displays beneath the image viewer for each asset. This feature provides additional viewing options, which allow researchers to compare images from diverse repositories in a single viewer. Please note that this feature does not display on audio-video or data-only records.

Click the Viewer button that displays below the default image viewer to launch Mirador in a new tab. The viewer will open and load the chosen asset. Please note this process can take up to a minute or more.

For multi-page assets Mirador offers offers a gallery style display of thumbnails for browsing.

Users can compare multiple non-sequential images from  American University Library's Digital Collections and/or any other repository using IIIF Mirador by inserting additional viewing panes which can be added using the "Add resource" button featured in the upper lefthand corner of the viewer.

To add a resource, users must paste the URL for the relevant asset's IIIF Manifest. Click the Manifest button to access this for any American University Library Digital Collection asset. The manifest will open in a new window and display as XML.

Then back in the Mirador viewer, paste the IIIF manifest URL of the object you wish to compare. Click on any thumbnail once the object’s images have loaded and you should see your chosen image appear in the slot beside your initial object. You can select a different viewing option for each object in each slot.
