    Abstract

    Missing web pages, URIs that return the 404 "Page Not Found" error or the
    HTTP response code 200 but dereference unexpected content, are ubiquitous in
    today's browsing experience. We use Internet search engines to relocate such
    missing pages and provide means that help automate the rediscovery process. We
    propose querying web pages' titles against search engines. We investigate the
    retrieval performance of titles and compare them to lexical signatures which
    are derived from the pages' content. Since titles naturally represent the
    content of a document they intuitively change over time.

    Abstract

    Dereferencing a URI returns a representation of the current state of the
    resource identified by that URI. But, on the Web representations of prior
    states of a resource are also available, for example, as resource versions in
    Content Management Systems or archival resources in Web Archives such as the
    Internet Archive. This paper introduces a resource versioning mechanism that is
    fully based on HTTP and uses datetime as a global version indicator.
