Navigating the IIIF Landscape: A Guide to Finding Images & Manifests

February 17, 2025

IIIF has revolutionized how we can access and interact with visual materials online. Yet, if you’re a researcher, educator or student, finding the right IIIF resources can be a challenge. To me, it still feels like detective work sometimes–especially when I don’t know exactly what I’m looking for in advance. Serendipitous discovery certainly hasn’t always worked for me, and over time, I found myself returning to the same go-to repositories, all while suspecting I was missing out on other valuable material.

After I launched liiive, one of the most frequent questions I got was where to find IIIF resources for specific research fields. Since my usual answer was a diplomatically worded ‘no idea’, I thought I’d turn to the IIIF community on Mastodon and Bluesky, asking people to share their favourite sources, repositories, links, and tips for finding material in the IIIF universe.

Finding good #IIIF resources can take a bit of detective work. I'd love to build a community-powered guide to the best collections for #liiive users. Here are some of my favorites: Digital Bodleian: digital.bodleian.ox.ac.uk, Rumsey Maps: davidrumsey.com, Smithsonian: collections.si.edu/search, Vatican: digi.vatlib.it, Yale Art: artgallery.yale.edu/collection. Have go-to sites or repositories? Please share—I'd love to feature them in my next blog post! #DigitalHumanities

Thanks everyone–I received some fantastic responses and discovered many resources I hadn’t come across before! Below, I’ve summarized the best tips I received, along with some of my personal favourites.

If you’re new to IIIF, the major collections are the obvious place to start. There are many out there–iiif.io maintains a useful list–but here are some of my personal favourites that I return to again and again:

  1. Digital Bodleian – A treasure trove of manuscripts, maps, and rare books from the Bodleian Libraries at the University of Oxford.

  2. David Rumsey Map Collection – I’m a map buff, and this collection is the definitive source. The IIIF manifest URLs are tricky to find (I’ll cover this in an upcoming post), but as far as I know, all maps are served via IIIF–and there are more than 100,000 of them!

  3. Smithsonian Collections – I love the diversity of this collection. Want to explore deep-zoomable photos of Neil Armstrong’s space suit? The Smithonian has you covered.

  4. Vatican Library Digital Collections – A vast collection of manuscripts, incunabula, archival materials, and coins.

  5. Yale University Art Gallery – A wonderfully rich and diverse collection of more than 190,000 items from across the world, spanning from antiquity to today.

Community Picks: Highlights & Hidden Gems

The responses I received covered a wide range of recommendations–both major repositories and lesser-known collections. Here are some standout picks:

IIIF aggregators and search platforms allow you to explore multiple collections at once, making it easier to sift through a wider variety of resources.

Tips, Tricks and Awesome Lists

Responses also mentioned useful resources that provide expert advice, helpful tools and curated collections of links that can help you navigate the IIIF universe more effectively.

Final Thoughts

IIIF has opened up incredible possibilities for researchers. The community is vibrant, friendly and growing, but finding the right resources can still take a bit of effort. Even once you’ve found a resource, tracking down the manifest URL for use in your preferred viewer (liiive, no doubt!) can require a bit of detective work (which I’ll cover that in an upcoming post).

A big thank you to everyone who shared their favorite IIIF sources and tips! If you have more to add, feel free to reach out by @-mentioning me on Mastodon or Bluesky, or by posting on the liiive community forum. I’d love to keep this post up to date with new sites, links, tips and tricks.

I hope this post has been helpful, introduced some new resources, and made it just a little easier to navigate the ever-expanding IIIF landscape.

Happy researching!
