Description:
Where do we define what bib info will be printed in the label?
When printing barcodes via "services > items > print item labels (item-03)" it uses item-copy-label-nn.xsl for inside labels and spine labels.
The xml includes a section called "bib-info", which appears as follows:
<xsl:call-template name="generic-line">
<xsl:with-param name="line" select="./bib-info"/>
<xsl:with-param name="width" select="'30%'"/>
</xsl:call-template>
By default this "bib-info" prints fields 100 and 245 (on a continuing line) and then the 260 on the next line.
Where is the bib-info format defined?

This is taken from usm50/bib_format:
item-copy-label 012

The 012 is taken from usm01/edit_paragraph
