Hi Hans and all, I did some more tests with the new bib mechanism in mkiv and hit a problem: the refcommand=authornum is broken. Minimal example: \setuppublicationlist[samplesize={{{The}}24},totalnumber=1] \startpublication[k=silktragedytragic,t=book, a={{Silk}},y=1996, n=1855,s=Sil96] \editor[]{Michael~S.}[M.~S.]{}{Silk} \pubyear{1996} \title{Tragedy and the Tragic. Greek Theatre and Beyond} \city{Oxford} \pubname{Oxford UP} \stoppublication \setuppublications[state=start, refcommand=authornum] \starttext \cite[silktragedytragic] \placepublications[criterium=cite] \stoptext I get !
