Hi Hans and all, the current beta has a problem with a bibliography entry I have in my project. I can't quite put my finger to it, but here's a fairly minimal example. It compiles without problems with an older version I happen to have on my disk (2011.01.06 17:08), but not with the current beta (2011.02.16 19:30): \startpublication[k=malkin2001,t=book, a={{Malkin}},y=2001, n=444,s=Mal01] \editor[]{Irad}[I.]{}{Malkin} \pubyear{2001} \title{Ancient Perceptions of Greek Ethnicity} \city{Cambridge (MA)} \pubname{Harvard UP} \stoppublication \startpublication[k=said2001,t=incollection, a={{Sa{\"\i}d}},y=2001, n=443,s=Sa{\"\i}01] \artauthor[]{Suzanne}[S.]{}{Sa{\"\i}d} \pubyear{2001} \arttitle{The Discourse of Identity in Greek Rhetoric from Isocrates to Aristides} \editor[]{Irad}[I.]{}{Malkin} \crossref{malkin2001} \pages{275--99} \pages{275--99} \pubname{Harvard UP} \stoppublication \setuppublications [refcommand=authoryear] \starttext \startsection[title=Test] \cite[said2001] \placepublications[criterium=all] \stopsection \stoptext It looks like it's the author's name Sa{\"\i}d, but this works in normal text, just not in a bibliography. Can you see what's wrong? Thanks, and best wishes Thomas
