Can't print bibliography

Question

It just does not work, no matter how I try. Currently I use

\bibliography{lit.bib}

before starting the document, then

\printbibliography{lit.bib}

before ending it. I can refer to entries in the bibliography just fine in text, the references will be made and named as they are in the bibliography, however the page on which I put the \printbib... command simply says "lit.bib"

What am I doing wrong?

I'm using pdflatex+makeindex+bibtex

Edit:

Version nr 2 gives the error "option clash for package biblatex"

Answer 1

You are mixing commands form bibtex and biblatex. If you use biblatex (i.e., \usepackage[...]{biblatex}, then the first command should be \addbibresource{lit.bib} and at the place where you want your bibliography to be printed, use \printbibliography. Nowadays, the default engine is biber (instead of bibtex, so you want to use bibtex you have to add backend=bibtex option to biblatex, \usepackage[backend=bibtex]{biblatex}).

If you do not use biblatex, then you should use \bibliographystyle{...} and \bibliography{lit}.

Answer 2

Your (modified) code, slightly more minimal than what you posted, runs fine on my system. I also corrected the syntax and I obtain a .blg file, so try this:

\documentclass[english,parskip=half]{scrartcl}

\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{lmodern}
\usepackage{babel}
\usepackage{microtype}
\usepackage{csquotes}
\usepackage{biblatex}

\usepackage[colorlinks=true,allcolors=black]{hyperref}
\addbibresource{lit.bib}

\begin{document}

\addto\extrasenglish{%
 \def\subsectionautorefname{Abschnitt} von Unterabschnitt auf Abschnitt
 \def\figureautorefname{Abb.}
}
....(more chapters here)

\nocite{*}
\printbibliography

\end{document}
