The Cleveland Museum of Art is proud to be an Open Access Institution, offering the public the ability to download, share, collaborate, remix, and reuse images of public-domain artworks from the museum’s collection, as well as metadata for the entire collection—all without asking permission. High-resolution images and data related to the CMA’s collection are made available under a Creative Commons Zero (CC0) designation.

What is Open Access?

Open Access content (images, data, software, and documentation) is content that the CMA publishes digitally online, free of charge, and without copyright and licensing restrictions. For more information about Open Access, visit the Creative Commons website for an  overview. Images, data, software, and documentation offered with Creative Commons Zero can be used in any application, from art making, education, digital media projects, scholarly research and publication to data science – all without fee or restriction.  

Half a Decade of Open Access

Five years ago, in January 2019, the CMA launched its Open Access initiative, which makes available to the public high-resolution images of more than half the artworks in our collection, completely free to view, use, remix, merchandize, and more.

2024 marks the fifth anniversary of the CMA’s Open Access collection. The online collection has been viewed six million times on its website, its API has been downloaded 45 million times, and its collections have been viewed nearly 300 million times on Wikimedia platforms. The CMA’s Open Access initiative has reached millions of users, serving the museum’s mission to “create transformative experiences through art for the benefit of all the people forever.”

Every year, we add numerous new images to the public domain. Notably, as of January 1, 2024, works by Théophile Alexandre Steinlen and Maurice Denis were added into the Open Access collection.

What is the Open Access Initiative?

As of January 23, 2019, the Cleveland Museum of Art is an Open Access institution, using the Creative Commons Zero (CC0) designation for high-resolution images and data related to its collection. This means the public now has the ability to share, collaborate, remix, and reuse images of public-domain artworks from the CMA’s world-renowned collection—all without asking permission. In addition, portions of collections information (metadata) for artwork records, both in the public domain and those works with copyright or other restrictions, are now available.

Why Open Access?

Open Access is a logical and exciting outgrowth of the CMA’s inclusive mission “to create transformative experiences through art, for the benefit of all the people forever.” The time is right to firmly bring our mission into the 21st century. With this move to Open Access, we have transformed not only access to the CMA’s collection but also its usability inside and outside the walls of our museum. By expanding access to the collection, we proudly contribute to best practice, both in the quality of images and the wealth of data we will release.

Open Access in 3-D

In September 2019, the Cleveland Museum of Art extended its Open Access policy to three dimensional (3-D) images of public domain artworks from its collection. Works with available 3-D image files are linked to open access objects in the Cleveland Museum of Art’s Collection Online with the 3-D icon and can be viewed and downloaded via Sketchfab.

It’s been especially exciting to watch as people from all over the globe discover and use these images in their own projects via the Creative Commons Search tool. Providing true access to digital knowledge and culture requires more than just publishing content online and calling it “open.” The CMA has exhibited great leadership in this space.
