 The buildDate metadata element is a timestamp, so is not user friendly. We can use one of our utility functions to format it.
+==== Total documents in library ====
+The above section shows how to add "this collection contains X number of documents" to a collection's about page. But what if we want to do that for the whole library?
+We can add up all the numDocs from each collection using 'sum', and count the number of collecitons using 'count':
+<code>
+<xsl:template match="/page/pageResponse">
+....
+<xsl:variable name="totaldocs" select="sum(/page/pageResponse/collectionList/collection/metadataList/metadata[@name='numDocs'])" />
+<xsl:variable name="totalcolls" select="count(/page/pageResponse/collectionList/collection)"/>
+<p>This library contains a total of <xsl:value-of select="$totaldocs"/> documents over <xsl:value-of select="$totalcolls"/> collections.</p>
+....
+</xsl:template>
+</code>
