Subject:        EMLS 2.2 / PURL / SHAKSPER Archive

In response to Norm Holland's note regarding PURLs, a PURL is like a URL except
that instead of pointing one directly at a resource, it points to a service
which then re-directs one to that resource.

Thus, the PURL

        http://purl.oclc.org/emls/emlshome.html

will, today and for the next few weeks, redirect to the URL

        http://unixg.ubc.ca:7001/0/e-sources/emls/emlshome.html

In the coming weeks, when EMLS must change servers within its sponsoring
institution (UBC) and as a consequence must also change its URL, the PURL can
still consistently direct users to our site.  In this way, a PURL is a useful
thing; while exact URLs might change with system reconfigurations and the like,
a PURL can remain stable, the exact URL to which it redirects being simply
updated.

The locational instability of many WWW sites is a bit of a contentious issue in
some circles, but PURLs seem a good measure to make up for this instability at
this time.  For EMLS, which is accessed by roughly 100 unique users per day, a
stable access point -- even if through a PURL -- is essential.

More information on PURLs can be found at the OCLC site:

        http://purl.oclc.org/

SHAKSPER members might also like to know that Interactive EMLS -- a section of
EMLS that houses Resources, Postprints, Preprints, and Conference Materials --
also houses a SHAKSPER Discussion List Archive, which can be found at

        http://purl.oclc.org/emls/iemls/shak/shak-L.html

As well, I'd like to take this opportunity to thank in advance our many readers
for their patience with EMLS' upcoming move.

Yours,
Ray Siemens
