Hi, I posted previously [http://www.ntg.nl/pipermail/ntg-context/2009/043675.html] but no one answer that. Is it possible to localizated bibliography module depending on \mainlanguage? I think for example in @inproceedings or @article in ams. It appears "number" for specifying the number of journal, but "number" is in english. It were useful if we could display "número" for \mainlanguage[es], "nombre" for \mainlanguage[ca], etc like we display tableofcontents or the title of references in \mainlanguage localization. For the other hand, is it possible to define second references like wikipedia? I plan to write a document that will have a normal bibliography citations (like \cite[bridson].... and display the book of Bridson) and a wikipedia-like citations for citing specifically paragraphs of text (that I want to display like wikipedia references \wikicite[This text appears in paragraph 2 of \cite[bridson] in a reject of ....]) Is it possible? Thanks in advance, Xan.
