Preventing the printing of bibliography items referenced after the bibliography is printed

Question

I am working on a project application that encompasses several "independent" parts:

• Project description
• CV
• Budget
• Misc.

The project description references some bibliographic items, and a bibliography is printed at the end, something like this:

\documentclass{article}

% ... some preamble options ...

\usepackage[backend=biber,natbib=true,sorting=none]{biblatex}
\addbibresource{bibliography.bib}

\begin{document}

% ... project description with several \cite{}...

% We print the bibliography after the project description:
\printbibliography[heading=none]

% ... here come CV, budget, etc with biblatex calls

\end{document}

The issue here is that I am extracting bibliographic info for the CV, e.g. using \citename{random_dude_2015}{author}, which are not referenced in the project description. However, biblatex is printing everything in the list of references, both the items referenced before \printbibliography and also those after. How can I prevent this from happening and force biblatex to print only the items referenced in the project description?

Answer 1

You can use refsegments to separate parts of your document

\documentclass{article}
\usepackage[style=authoryear, backend=biber,natbib=true,sorting=none]{biblatex}
\addbibresource{biblatex-examples.bib}

\begin{document}
\cite{sigfridsson,geer}
\printbibliography[segment=\therefsegment]
\newrefsegment

And later on: \fullcite{worman}
\end{document}

this leaves a potential for a shared bibliography and keeps disambiguation features. Alternatively, you can use the refsegment environment instead of the \newrefsegment command.

\documentclass{article}
\usepackage[style=authoryear, backend=biber,natbib=true,sorting=none]{biblatex}
\addbibresource{biblatex-examples.bib}

\begin{document}
\begin{refsegment}
\cite{sigfridsson,geer}
\printbibliography[segment=\therefsegment]
\end{refsegment}

And later on: \fullcite{worman}
\end{document}

If you prefer an approach where both parts of the document are completely separate, use refsections

\documentclass{article}
\usepackage[style=authoryear, backend=biber,natbib=true,sorting=none]{biblatex}
\addbibresource{biblatex-examples.bib}

\begin{document}
\cite{sigfridsson,geer}
\printbibliography
\newrefsection

And later on: \fullcite{worman}
\end{document}

Here again, a refsection environment is also available.
