Currently Koha can show the "Show volumes" link for set and traced series records. With a search in the background we check for existing volumes and display of the link depends on their existence. The same should be implemented for serial records that can also have separate records in some libraries for bound volumes of serial issues. Currently we use this XSLT to always show the link for serial records (or never, depending on CSS): <xsl:template name="serial_volumes"> <xsl:param name="gui"/> <xsl:param name="UseControlNumber" /> <xsl:variable name="SearchUrl"> <xsl:call-template name="SearchUrl"> <xsl:with-param name="gui"><xsl:value-of select="$gui" /></xsl:with-param> </xsl:call-template> </xsl:variable> <xsl:if test="substring(marc:leader,8,1) = 's' and not(substring(marc:leader,20,1)='a' or substring(marc:controlfield[@tag=008],22,1)='m')"> <span class="results_summary serial_volumes"><span class="transl label en">Volumes: </span><span class="transl label de-DE">Bände: </span> <a> <xsl:choose> <xsl:when test="$UseControlNumber = '1' and marc:controlfield[@tag=001]"> <xsl:attribute name="href"><xsl:value-of select="$SearchUrl"/>q=rcn:<xsl:value-of select="marc:controlfield[@tag=001]"/>+not+(bib-level:a+or+bib-level:b)</xsl:attribute> </xsl:when> <xsl:otherwise> <xsl:attribute name="href"><xsl:value-of select="$SearchUrl"/>q=ti,phr:<xsl:value-of select="translate(marc:datafield[@tag=245]/marc:subfield[@code='a'], '/', '')"/></xsl:attribute> </xsl:otherwise> </xsl:choose> <span class="transl en">Show volumes</span><span class="transl de-DE">Zeige Bände</span> </a> </span> </xsl:if> </xsl:template>
