For the maps, one of the key characteristics is the information about the scale of the map (in MARC 21 - in the field 255: https://www.loc.gov/marc/bibliographic/bd255.html). Currently, we do not display it neither in intranet view, nor in OPAC. MARC21slim2intranetDetail.xsl and MARC21slim2OPACDetail.xsl could be corrected.
