# How to use biblatex to have a nested bibliography with a nested toc?

Biblatex is really cool, and allows the subdivision of the bibliography into sections based on different filters : for exemple, if I want to print only the articles of my bibliography, I can write :

\printbibliography[type=article, title={Articles}]


\printbibliography[heading=bibintoc, type=article, title={Articles}]


and my bibliography of articles now figures in my toc.

The thing is, I would like to have a nested bibliography : the table of content would look like something like this :

which I achieve easily by writing :

\printbibliography[
title={Bibliography}
]
\printbibliography[
type=article,
title={Articles}
]
\printbibliography[
type=book,
title={Manuals}
]


BUT the above code only gets me the toc I want, and not the bibliographies I want. I don't want three bibliographies. I want a "section-like" title saying "Bibliography" (BUT without the numbering, because bibliographies are supposed to not have a numbered title), and then two sub-bibliographies, whereas when I write the above code I have a complete bibliography and then two sub-bibliographies :

Writing only :

\printbibliography[
type=article,
title={Articles}
]
\printbibliography[
type=book,
title={Manuals}
]


doesn't get me what I want neither :

• the toc merges the entries for the two sub-bibs with the entries for the previous section

• the sub-bibs are printed with "subsection-like" titles, but there is no "section-like" title reading "Bibliography".

Writing :

\section{Bibliography}
\printbibliography[
type=article,
title={Articles}
]
\printbibliography[
type=book,
title={Manuals}
]


almost gets me what I want, except for the part where the bibliography title is numbered, which ideally it wouldn't.

In my preambule, I have :

\usepackage[
backend=biber,
defernumbers=true,
style=numeric,
backref=true
]{biblatex}


And my .bib file looks like this :

I would very grateful if someone knew and explained how to do that, I've been scratching my head for a bit now.

• I suggest you include a \section before both \printbibliographyies. Or revert back to bibintoc and use \chapter (provided you are using the book class). Aug 23 '17 at 21:38
• @logo_writer : It's not exactly what I want (with a \section command, you get the title to be numbered which I don't want), though it's the closest to what I'm trying to obtain. I'm sorry my post wasn't more clear and precise, I edited. Aug 24 '17 at 9:01
• If I understand your problem right, you need a no-number section heading? In this case: \section*{Bibliography} does the trick. if you want to change the style of your headings not showing the numbering (but still counting) I'd take a look here: tex.stackexchange.com/questions/136527/… Aug 24 '17 at 11:57
• @pharmarkus : Yes! I didn't know about no-number sections, I'll be sure to check the link you provided. Thank you very much. Aug 24 '17 at 15:34

Is this what you want? (The bibliography.bib is the one you posted).

\documentclass{book}
\usepackage[
backend=biber,
defernumbers=true,
style=numeric,
backref=true
]{biblatex}

\begin{document}
\tableofcontents
\nocite{*}

\chapter*{Bibliography}
