Hallo, I've started to add bibliography to my documents. Now I have some questions: 1. How can I handle multilanguage bibtex files (entries in German and English)? I'm writing english texts but I need to cite german documents and in all german references all capital letters are trasfered to small ones. 2. How to encode glyphs/german umlaute (öäüß) in the bibtex file? It seems that I can not use utf for that. 3. I have in the bibtex field: "comment = {genauere Analyse des Papers nötig!}," some comments. They are added at the end the individual reference. Is there a possibility to suppress this field? 4. is there a way of citing by bibtex key? (to get (Hameury2005) for the entry @ARTICLE{Hameury2005,...)). I think that is nice to have during writing the document and only to change this in the final version. Many thanks Wolfgang
