Why??? This site might well be moved to a server of a different provider, so - if you don't like to end up with one of those annoying 'HTTP 404 - File not
found' error messages - use this PURL rather than the actual URL you might
see in your address, status or whatever-it-might-be-called bar.

For the curious: a PURL is a Persistent Uniform Resource Locator.
Functionally, a PURL is a URL. However, instead of pointing directly to the
location of an internet resource, a PURL points to an intermediate
resolution service (a "resolver"). The PURL resolver associates the PURL
with the actual URL (which we - promised! - keep up-to-date) and returns
that URL to you; from here onwards the URL transaction is completed as
usual. In wwweb parlance, this is a standard HTTP redirect.

Got interested? Read all about it on the PURL resolver site of the OCLC
Online Computer Library Center at http://purl.oclc.org
