What is IIIF? a flag with iiif logo
iiiftriple aye eff – is the International Image Interoperability Framework. It is an open standard to deliver high resolution images for deep zooming from galleries, libraries, archives, and museums (GLAM).
A iiif manifest contains information how to access a digitized page or an entire book at a iiif provider’s web site. It also delivers metadata on the iiif book.
– More info at iiif community home

Dedicated web tools are needed to open iiif manifests – much like Adobe Reader or the Preview app on Macintosh which both display pdf documents.
Mirador and Universal Viewer are most common. But Chronoscope World is capable to open iiif manifests as well.

Import IIIF Manifest Links

Many libraries and archives offer their collections also as iiif. Usually a link to a iiif manifest is provided on the item page.

Copy’n’Paste or Drag’n’Drop a manifest link to Chronoscope World to open the iiif page or the entire book.

On success, a table of thumbnails gives an overview of the book’s content.


  1. Open Justus Danckerts’ Atlas from 1715 at e-rara by ETH Zurich
  2. Find and copy the manifest link from the lower section of the page.
  3. Import the link into Chronoscope World.

Learn how to import geoLinks into Chronoscope World because iiif manifests are basically formatted text files on a iiif provider’s web server. The web address is needed to open the manifest which can contain a single image or an entire atlas or book.

Chronoscope World displays maps from more than 66 libraries, archives and museums at their correct location. But you can import any iiif manifest from any iiif provider and browse the pages.

Imported books remain available until the browser window is closed or reloaded.

However, sharing a ChronoLink to an imported iiif book is possible as the link contains a parameter for the original iiif manifest.

Warning Mind, that usually imported pages are displayed south of Ghans at 0° latitude - 0° longitude. Only for some libraries bounding box locations are available; among them are Yale, e-rara, and e-manuscripta.

Power user tip:
It is possible to drag one iiif book after another onto the Chronoscope. The table of maps does not even have to be closed. That makes it possible to siff though dozens of books with thousands of pages quite efficiently.
This is useful if you do not know quite for sure what you are looking for. Just open a book with a drag gesture and have a glance at the thumbnails.

A few portals offer the iiif info on the search result pages. In this case it is possible to drag the iiif icon directly onto Chronoscope’s browser window with out loading the iiif book’s details page.

Browser Extension DetektIIIF

detektIIIF2 is a browser plugin for Firefox, Chrome and Brave that automatically detects IIIF‑compliant resources and thus facilitates the collection of digital iiif manifests.
