# Is there a way I can manually reset or clear the citations in biblatex?

Biblatex already provides options for citereset and refsection which make it easy to set up multiple (sub-)bibliographies for a document. However, the document I am creating uses manual partitions (above the level of "part") for my own purposes, as a form of "volume" in the wider work.

(The document is set up something like we see here.

I want citations to be consistent across parts, but when I reach one of these manual divides to a different "volume", I would like a separate citations section.

Is there a way I can manually reset the list of citations - and their numbers - at this point?

To add to the complication (potentially), I would like to be able to \nocite{*} to do a book-wide bibliography, through all volumes at the end.

I'm using biblatex with the tufte-book class, as well as the subfiles class for managing sub-files.

UPDATE:

So, according to the documentation of biblatex there is a \citereset command, however - compiling with latexmk -pdf, that is - I find that it doesn't seem to do this.

I.e., with the layout:

...the end. (The end of the last part in "Volume I")

% print bibliography for Volume I
\printbibliography
\citereset

% (code for manually ending this volume / starting next volume goes here)
\part{My Part}
\chapter{My Chapter}
% (no citations take place here)


...

...the end. (The end of the last part for "Volume II")

% print biliography for Volume II
\printbibliography
\citereset

% print bibliography for entire book
\nocite{*}
\printbibliography


... what we find is that every bibliography has all the same references (the bib file I'm testing against in this case only has one reference).

• Welcome to TeX.SX! I must confess I'm a bit confused here with your requirements. I believe refsection is the tool for what you are asking for, as far as I understand. To reset the numbering you should look to printbibliography's option resetnumbers (which requires global option defernumbers). But then, if you reset the numbering for each part, how do you intend to obtain "consistent citations across parts" or especially a "book-wide bibliography"? – gusbrs May 4 '18 at 0:46
• @SamWalls, you don't need the logical section to associate with the refsection. refsections can be issued manually at any point in the document with the refsection environment or with \newrefsection (it must make sense, of course, and refsections can't be nested). – gusbrs May 4 '18 at 1:09
• As to the global bibliography, if you reset the numbering per "volume", which number should the references get in the book-wide bibliography? – gusbrs May 4 '18 at 1:10
• from your update, I also think you are misusing \citereset. This command resets the citation tracker (used for the likes as "idem, ibidem, op. cit." short forms and so on). – gusbrs May 4 '18 at 1:17
• I think the ideal here would be for you to provide us with a minimal working example (MWE)/ MWEB. A short compilable document which has the basic logical structure of what you are trying to achieve, your bibstyle/citestyle and some sample bibliographic entries. – gusbrs May 4 '18 at 1:19

In my view, the question isn't very clear as to specifics, which makes it difficult to answer. But here is a general structure you could use to do what I think you are trying to do.

Notice I'm using \newrefsection to divide at your "above part volume level" and provide structure for you to generate a book-wide bibliography based on a category "workscited".

\documentclass{book}

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

\DeclareBibliographyCategory{workscited}

\defbibenvironment{bookwidebib}
{\list
{}
{\setlength{\leftmargin}{\bibhang}%
\setlength{\itemindent}{-\leftmargin}%
\setlength{\itemsep}{\bibitemsep}%
\setlength{\parsep}{\bibparsep}}}
{\endlist}
{\item}
