Thank you for the instructions on how to make one's own style. I only need to change the formatting in the bibliography list, the formatting of the notes in the text is entirely up to the requirement. A strange effect (full MWE in attachment): \btxdoifelse {address} { {\btxspace \emdash \btxspace \btxflush{address} \btxcomma} } \btxdoifelse {year} { {\btxspace \btxflush{year} \btxperiod} } gives "year 2000", but throw out the "address" part, and the year goes straight without the 'year' part. \btxdoifelse {year} { {\btxspace \btxflush{year} \btxperiod} } if you add publisher between the address and the year, then it says "publisher Brill" \btxdoifelse {publisher} { {\btxspace \btxflush{publisher} \btxcomma} } Where does it pull it up from?
