Best Answer

Referring to your comments I assume that you want a bibliography at the end of each chapter using biblatex and biber. Important is the option refsection=chapter combined with the heading subbibliography at the \printbibliography command in each chapter.

You can compile the example code below by:

  1. pdflatex document.tex
  2. biber document
  3. pdflatex document.tex
  4. pdflatex document.tex
