Since Caesar has been killed, there are problems with some special kind of entries: those who cannot be parsed correctly by biblio.C. The citation style choice is empty in that case and I cannot chose a style. I have collected a few of those entries, some are from xampl.bib
Just one example: If I have an entry with an empty year field, bibtex displays it as "Name (o.J.)" [o.J. = "ohne Jahresangabe" = "no year"], I can do: \citet{Spi} ==>> Spitzmüller (o.J.) \citep{Spi} ==>> (Spitzmüller, o.J.) \citealt{Spi} ==>> Spitzmüller o.J. \citealp{Spi} ==>> Spitzmüller, o.J. \citeauthor{Spi} ==>> Spitzmüller \citeyear{Spi} ==>> o.J. \citeyearpar{Spi} ==>> (o.J.) but not in current lyx-cvs. So I'd vote for reanimating Caesar. Juergen. Some (correct!) examples that are failing: @Misc{Spi, Author = {Spitzm\"uller, J\"urgen}, Title = {An unpublished essay}, HowPublished = {Private copy}, } @MANUAL{manual-84, key = "Manmaker", title = "The Definitive Computer Manual", year = "1984", } @BOOKLET{booklet-87, key = "Kn{\printfirst{v}{1987}}", title = "The Programming of Computer Art", year = "1987", } @UNPUBLISHED{unpublished-minimal, author = "Ulrich {\"{U}}nderwood and Ned {\~N}et and Paul {\={P}}ot", title = "Lower Bounds for Wishful Research Results", note = "Talk at Fanstord University (this is a minimal UNPUBLISHED entry)", }
