first to all sorry for my english, isn´t me native language and is difficult for me. It´s the first time that i use this forum for that reason.
Now, i´ll try to explain my problem. I need to do multiple bibliographies, one for each chapter, and for it i´m using the package \usepackage[sectionbib]{chapterbib} (I'm using TexnicCenter), and using a file .bib for each one of them.
After to compilate, in the end of each chapter appears the respective bibliograpy, but in the part of the text where's the cite (\cite{....}), in pdf file (Latex=>PDF) appears [?], even after two or three compilations.
Is the first time that i have this problem, but also is the first time that use \usepackage[sectionbib]{chapterbib}, so think that the problem is there, although the bibliographies are created in each chapter after compilation, means that files .bib are ok and to use \usepackage[sectionbib]{chapterbib} would be right, so i don´t know where is my mistake
\citethen bibtex generates the bibliography from the .bib file using the list of \cite, then you need to run latex again to include the generated bibliography – David Carlisle Oct 10 '14 at 13:37
