Hi, It seems that the 'sorttype' option is not recognized in '\setupbtxrendering'. I tried all the different values (page 25 in mkiv-publications.pdf) but nothing changes. The log files suggests that the option is not read correctly. For example : % test-biblio.tex \usebtxdataset[biblio.bib] \setupbtxrendering[sorttype=index] \startdocument \startchapter[title=First chapter] \input ward \cite[ward,knuth]\blank \placelistofpublications \stopchapter \stopdocument % end % biblio.bib @book{knuth, title = "Title", author = "Knuth", publisher = "Publisher", year = "2019", } @book{ward, title = "Title", author = "Ward", publisher = "Publisher", year = "2019", } % end give the following line in the log file : publications > list > collecting entries using method 'global' and sort order 'default' Thanks for the help. -- Romain Diss
