This workshop gives a step-by-step introduction to working with IIIF images in research and in public outreach. The focus is on medieval manuscripts but this can easily be adapted to other types of objects. It contains useful practical examples and assignments for the participants. Contact us to book a live (online) session, or discover the workshop at your own pace.

Live workshops IIIF

This page is used during live workshops by Mmmonk at higher education and GLAM institutions (e.g. KU Leuven, European Lettering Institute, Ghent University, Columbia University). Contact us if you would like to introduce students and staff at your institution to the benefits of working with IIIF in education, communication and research.

IIIF (International Image Interoperability Framework) is a digital innovation that makes it easier to work with digital images of cultural heritage objects. It erases the boundaries between digital collections at various institutions. The technology is adopted by a growing number of institutions, such as the BnF, Vatican Library, British Library, Getty Museum, and many other large and small institutions across the world. A quick introduction on what IIIF is and how it works can be found here.

IIIF presents many advantages for research and education. By minimizing the need to download and duplicate images, IIIF also helps to reduce the ecological impact of digital humanities.

Good to know before you start

  • Bookmark this page. We'll often refer to external websites.
  • Every digital object (book, painting, drawing, sculpture...) that is available in IIIF has a manifest URL. The manifest URL is the key to use this object in IIIF tools. IIIF is used by a growing number of institutions, but is not yet used everywhere, so the object of your choice might not yet have a manifest URL.
  • IIIF tools and websites do not depend on the institutions (libraries, museums, archives) that manage collections. They are developed by a community of IT specialists and special collections specialists.
    • Viewers are designed to consult manuscripts. Universal Viewer and Mirador are two of the most widely used IIIF viewers.
    • Guided viewing tools are designed to create virtual tours. Mmmonk works with the Exhibit tool, but there are a number of other tools available.

Find and copy the manifest URL

What are we looking for?

A manifest is the "packaging" in json code around the digital images and metadata. Each manifest has a URL. This URL is stabile and is the key to work with the images and metadata.

A manifest URL contains the words IIIF and manifests. For instance:

Some examples of where and how to find manifest URLs

Mmmonk: Go to the page of a manuscript (e.g. this breviary) > the link is right below the viewer. For this workshop we have gathered some interesting manifests for you to play with: consult the list on this page.

Specific institution: Look for the words 'IIIF manifest URL' or the IIIF logo in the metadata (descriptions) of an object in the institution's online catalogue. Some examples:

  • Ghent University Library > go to ‘For developers’;
  • KU Leuven > go to ‘View online’ > open the manuscript in Teneo > go to ‘information’ (‘Permalink IIIF manifest’).
  • Gallica BnF > click on the IIIF logo in the left sidebar > click on the information 'i' logo in the right upper corner to open the metadata for the object > the manifest is at the bottom of the metadata
  • British Library ... don't include manifest URLs in their records.
  • Cambridge University Digital Library Many options, among others the obvious 'Manifest URL' button.

World wide: Biblissima IIIF Collections: This website gathers all of the available manifests of manuscripts and rare books (and is an awesome website in general for manuscripts research).

Copy the URL

Found it? Then copy the URL (i.e. the information in your browser's address bar). This is the key you need. If the manifest should open, you will see a page filled with json code. You don't need the code, only the URL.

Share a detail on an image via Universal Viewer

You have found an interesting detail in a manuscript and wish to share this with someone or to save it for yourself. Instead of downloading the image or taking a screen shot, you can share or bookmark a URL with coordinates.

How to

  1. Select and copy the manifest URL of the object of your choice, for instance
  2. Open the website
  3. Copy the URL to ‘Paste the URL of a IIIF manifest here to see the UV in action!’
  4. Browse the manuscript and zoom in on an interesting detail. (Watch how the coordinates in the URL change as you zoom or move. The coordinates make it possible to share a specific area of an image.)
  5. Copy the URL with the coordinates or use the share button in the viewer. Share the URL in a message, copy it to a document, or bookmark the page.


Find the coat of arms of Abbot Raphael de Mercatellis (f. 3r) in Ms. 109 from Ghent University Library. Zoom in on the detail and share or save this detail.

manifest URL Ms. 109:

Compare manuscripts in Mirador

You have found an interesting manuscript at the British Library and wish to compare it with a manuscript from Bruges Public Library and a painting from the Getty Museum in Los Angeles. Each of these institutions has their own viewers, with specific rules and functionalities. This can be burdensome for researchers, going back and forth between websites. The Mirador viewer allows you to gather these objects (images + descriptions!) in a single uniform viewing environment.

How to

  1. Select and copy the manifest URL of your object.
  2. Open the website (Close the examples by Van Gogh and of Krishna.)
  3. Hit ‘start here’.
  4. Hit ‘add resource’.
  5. Add the manifest URL and hit ‘add’. Your object is now the first in the list of resources.
  6. Click on your object to add it to your collage.
  7. Repeat these steps as often as you wish to add objects to your collage.
  8. Save your collage by clicking on the three dots in the menu on the right. Hit 'export workspace' > ‘view workspace configuration’, select the body of text and save it to a document or notepad for later use. Open a collage by importing the saved text into ‘import workspace’.

Assignment 1

Compare the Liber Floridus manuscripts at Ghent University Library (Ms. 92) and at Chantilly Bibliothèque et archives du château (Ms. 724).

Ms. 0092 manifest URL:

Ms. 724 manifest URL:

Assignment 2

Find images of a specific iconographical topic using the Biblissima Portal. Make a collage in Mirador with at least three images.

Tip: Take into account that the website's descriptions are written in French and/or English. Searching for terms like Apocalypse, dragon, Jerusalem… yields the best results for this exercise.

Create a virtual tour with Exhibit

You'd like to create an online exhibition on one or more manuscripts. Instead of collecting, cropping and uploading images, you can collect manifest URLs in the Exhibit tool. You can even alternate the images with YouTube videos for a more dynamic effect. Visitors can zoom in and out on the images and can easily consult the metadata of the images. As a result, the images are not separated from their context!

How to

  1. Go to > ‘Create an Exhibit’
  2. Choose the format (Kiosk plays automatically, Scroll let's visitors scroll through the tour, Slide is a slideshow, Quiz presents multiple choice questions)
  3. Fill in the required fields and ‘create exhibit’. You can always come back to this menu to make changes.
  4. Bookmark the URL or save it in a document. Exhibit does not use accounts and log-ins. The URL is the only way to return to your work.
  5. Click ‘add item’.
  6. Paste a manifest URL in the bar at the bottom and click 'import'.
  7. Select this resource in the list of resources and hit 'add to exhibit'.
  8. Browse through the manuscript to the page of your choice and zoom in on the detail of your choice.
  9. Hit the '+' bar ('add new'). This opens the annotation module. Write your annotation. You can still modify the image at this point.
  10. Hit the 'check' button below the annotation to save the annotation and the image. Would you like to show another page in the same manuscript? Then browse through the manuscript to the detail of your choice, click on '+', and create a new step in your tour.
  11. Add as many items/resources as you wish. This can also be a YouTube video.
  12. Go to 'preview' to preview your tour. Hit 'share' to share or embed your tour.


Error report when you import a manifest? Is it possible you've already added this manuscript and that it is already in your list of resources? If not, check the URL for errors.


Select a few manuscripts (e.g. from the Mmmonk workshop list) and create a tour or quiz. (Bookmark the URL of your workspace!)

Embed a viewer on your website

You have written a blogpost or have created an online course on manuscripts (or other objects). Instead of uploading static images to your website, you can embed a IIIF-viewer to offer a richer experience to your audiences.

This viewer is embedded on this webpage. You can still zoom in or out, leaf through the book, and you have access to the metadata.


Enjoy the functionalities of a viewer (vs. a static, flat image): show a detail but keep the option to zoom out + direct access to metadata descriptions + high resolution + quick + no need to download/save/crop/upload/host images (and pay for server capacity and hosting).


How to

  1. Retrieve the iframes or div embed code via Universal Viewer (> ‘share’). This functionality is sometimes also available in customized viewers on institutional websites.
  2. Embed the iframes code as an alternative for an uploaded jpg in the CMS of your website. Ask your supplier to provide this option when you design a website.

When you use the iframes code, you (the editor of the webpage) will be able to zoom in on a specific detail (via URL coordinates). This is not an option with div code.

Download an image

Although IIIF makes it easy to return to online images (and even details on them), sometimes you just want to download an image. No problem, this is still possible with IIIF!

How to

  1. Go to
  2. Paste the manifest URL into the bar and hit ‘view’.
  3. Click on the download logo in the lower left corner of the viewer. Select one of the options. 'Source image file (tiff)' will download the image as it was uploaded by the institution.
