RIS and Bibtex exports from staff side and OPAC edited to allow for additional publisher RDA tag (264). Script will look first for 264 then fall back to 260 when pulling publisher data from MARC21 records. Test Plan: 1. Create RDA and non RDA record 2. In OPAC, export both as RIS and Bibtex - verify publisher information is exported 3. On staff side, export records as RIS and Bibtex, verify publisher information is exported. Signed-off-by: Chris Cormack <chrisc@catalyst.net.nz> Signed-off-by: Katrin Fischer <Katrin.Fischer.83@web.de> Fixed some tabs pointed out by the QA script. Works nicely in my tests, no regressions found. Signed-off-by: Galen Charlton <gmc@esilibrary.com>
