Hi I have
The following setting in my custom file '(org-ref-formatted-citation-formats '( ("org" ("misc" . "${author}, /${title}/ *${howpublished}* ${url} (${year}).") ("article" . "${author}, /${title}/, ${journal}, *${volume}(${number})*, ${pages} (${year}). ${doi}") ("inproceedings" . "${author}, /${title}/, In ${editor}, ${booktitle} (pp. ${pages}) (${year}). ${address}: ${publisher}.") ("book" . "${author}, /${title}/ (${year}), ${ISBN}, (pp. ${pages}) ${address}: ${publisher}.") However when I want to export a book reference to HTML, the ISBN field is not inserted. Any idea what is wrong? Thanks Uwe Brauer -- Warning: Content may be disturbing to some audiences I strongly condemn Putin's war of aggression against the Ukraine. I support to deliver weapons to Ukraine's military.
