About this data
This page tracks the decay of archived museum exhibit URLs over time, revealing how often institutions fail to preserve digital access to cultural content. The data shows the percentage of URLs returning 404 errors and the median days until decay, based on systematic monitoring of public museum archives. It highlights a widespread but overlooked failure in digital preservation, where historical exhibits vanish despite being stored in online archives.
Sources
Every figure on this page was read from these pages.
No existing source systematically tracks URL decay in public museum archives as a global phenomenon. While general web preservation tools (Wayback Machine, HTTP Archive) and articles on link rot exist, none focus specifically on museum exhibit URLs or provide a dedicated tracking system.
