Hi Taco, I just noticed that my reference list has a quirk with the inproceedings entries reading: Author, A and Author, B. (2000). Article title. In Editor, A., Editor, B. and Editor, C., editors, Title of book, pages 1-10. Publisher. Note that it should read "... In Title of book, editors Editor, A., Editor, B. and Editor, C, ..." My bib entry reads: @inproceedings{Test:2000, Author = {Author, A. and Author, B. and Author, C}, Booktitle = {Title of book}, Pages = {1-10}, Title = {Article Title}, Publisher = {Publisher}, Editor = {Editor, A. and Editor, B. and Editor, C.}, Year = 2000} I believe the bug is in bibl-apa.tex \setuppublicationlayout[inproceedings]{% \insertauthors{}{ }{}% \insertpubyear{(}{). }{}% \insertarttitle{\bgroup }{\egroup. }{}%% \inserttitle {In \inserteditors{}% {, editor\ifnum\getvalue{editor@num}> 1 s\fi, }% {}% \bgroup\it}% {\egroup \insertseries {\insertvolume{, number }{~in }{ }}% {}% {}% \insertchap{\unskip, }{ }{ }% \insertpages {\unskip, pages~} {\insertcity{, }{. }{. }} {\unskip. }% \insertorganization {}% {\insertpubname{, }{. }{. }}% {\insertpubname{}{. }{}}% was {, }{. }{} }% {In \insertcrossref{}{}{}% \insertchap{\unskip, }{ }{ }% \insertpages{\unskip, pages~}{. }{\unskip. }% }% \insertnote{ }{.}{}% }
