Explore is an image search tool designed to trace the circulation of images across millions of historical illustrated publications dating from the 19th century onward.
It was created for the Visual Contagions Project at the College of Humanities, University of Geneva (SNSF 2021–2026), under the direction of Prof. Béatrice Joyeux-Prunel.
The available dataset currently includes more than 3.5 million issues from approximately 81,000 illustrated journals published between 1797 and 2021 in 51 countries worldwide.
All journals are open access, some of them provided in IIIF format, and distributed by international partner institutions.
