Grouping/sorting entries of the bibliography - biblatex

I want to group entries of the bibliography based on my own preference (not by entry type). Right now I'm adding my bibliography file with all the entries at the end of my document like this:

\usepackage[style=numeric]{biblatex}
\bibliography{src/bib/Literaturverzeichnis}

\begin{document}

\end{document}


I am looking for a way to create some subsets of the bibliography entries and list them one after another up, seperated by a blank line and a specific topic for each subset.

My desired bibliography should look like this:

Literaturverzeichnis

CaptionSubset1
book1
book2

Caption Subset2
book3
article1

• Use biblatex + biber. – Ulrike Fischer Nov 12 '15 at 10:50
• You can use keywords, bibliography categories, or more elaborate filters and checks. If you use categories the big plus is that you can use \bibbycategory to loop over all categories automatically. – moewe Nov 13 '15 at 6:13
• Using categories has the advantage (or disadvantage) that the association with a particular category does not have to be decided on in the .bib file but dynamically in the document (though I believe it is possible to automate this process based on keywords if you like). – moewe Nov 13 '15 at 7:31

I did this by adding tags to the bibentries like this:

@book{Book1,
author = {John Doe},
title = {Hello World},
year = {2001},
keywords = {Caption1},
}

@book{Book2,
author = {Max Mustermann},
title = {This is only a test},
year = {2015},
keywords = {Caption2},
}


Then you should be able to do this:

\begin{document}

I am citing \cite{Book1} and \cite{Book2} in the text.

\printbibliography[keyword=Caption1, title={First Bibliography}]
\printbibliography[keyword=Caption2, title={Second Bibliography}]

\end{document}


and have as many mini-bibliographies according to your wishes. You will have to set keywords for every bibentry, though.

It will look like this:

I hope I could help!

Edit: as stated in the comments, the correct argument is keywords and not keyword. For adding the bibliography you have to specify e.g. keyword=Caption1, though.

• I added for each entry in the bib file a keyword but it doesn't work in my document, and added a print instruction for each keyword but there will be no bibliography. No errors too. Did you tried it? – d4rty Nov 12 '15 at 15:09
• The correct name for the field in biblatex is keywords (mote the s at the end). You will also need to wrap all fields in curly braces (or quotes if you must) for them to be processed correctly. – moewe Nov 13 '15 at 6:06
• @d4rty See my comment above and this – moewe Nov 13 '15 at 6:14
• I am sorry, I was slacking! Edited – Ian Nov 13 '15 at 8:50
• You are missing a comma after Book, the citekey needs to be separated by a , from the rest of the entry. I think your answer would benefit from a full example showing the code in situ. If you find the time, you can also explain bib categories and highlight the difference. – moewe Nov 13 '15 at 8:57
