About this data

This page measures the decay of public library event calendars, a critical but often overlooked digital presence for community institutions. It tracks two key metrics: the percentage of libraries with dead event calendars and the median lifespan of these URLs in days. The data is collected by systematically checking calendar links across a representative sample of public libraries over time. Understanding this decay reveals how well public institutions maintain their digital footprints and where they may be failing to preserve essential community resources.
