+RSS (RDF Site Summrary or Really Simple Syntication) is a web feed format to publish frequently new or updated ELOG entries. This is a bit like the email notifications present in ELOG, but the RSS system does not go through an email reader, but through a dedicated RSS reader. This helps to seperate ELOG updates form other email or spam. An RSS "channel" can be subscribed to, so one gets notified whenever a new or updated entry exists. One can either use a dedicated RSS reader or aggregator, or use the RSS functionality of a web browser, such as Firefox or Google Reader.</p>

+<p>
+To obtain the RSS feed, one simply has to request the file <b><code>elog.rdf</code></b> from a logbook. For the ELOG forum, one can enter the URL</p>
+<code>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
+<a href="https://midas.psi.ch/elogs/Forum/elog.rdf">https://midas.psi.ch/elogs/Forum/elog.rdf</a>
+</code>
+<p>The browser then offers the possiblity to subscribe to that logbook:<p>

+
+<p>In case of "Live Bookmarks" in Firefox, new logbook entries automatically appear in the bookmark list:</p>

+<p>Standalone RSS reader can also notify the user of new entries with dialog boxes and sounds. For a list of availabel RSS aggregators, see <a href="http://en.wikipedia.org/wiki/Comparison_of_feed_aggregators">here</a>.</p>
