The increasing digitiza-ti on and the emergence of new data-sharing practices change our understanding of how cultural heritage is de -fined, collected, and exhibited. We must pay particular attention to the ways in which digital interfaces curate history. Crowdsourcing, social media, linked open data, and other open science practices challenge the current practices of cul-tural heritage institutions, owing to the established structures between and within them and the char-acter of the networked publics involved. Howev-er, such challenges also open new opportunities for wider negotiations of cultural heritage and rethinking what cultural heritage institutions and practices are. This spe-cial issue brings together scholars from different disciplines to provide critically and empirically grounded perspectives on the datafication of cul-tural heritage institutions' exhibition and collection practices.
