Search engines regularly crawl the web taking vast snapshots of sitecontent. Because previous crawls are not archived, however, searchresults pertain only to a single, recent instant in time. Search engine users are unable to request pages discussing UK politics in2001, for example. The Internet Archive, an organization dedicated to maintaining such snapshots of the Internet, provides access to many previous web crawls, but lacks a search facility. Users of the ``Way Back Machine'' must provide a specific URL for which they want a listof snapshots organized by date. This short paper describes Chronica, atemporal search engine that indexes Internet Archive crawl data in order to provide search results spanning user-specified time ranges. Chronica can generate graphs showing query result hit counts across a given time span and even side-by-side comparisons of different query results. These graphs can be used to, among other things, track a term's popularity over time for marketing or academic research purposes.
