[Tex/LaTex] Reverse numbering in biblatex bibliography with different categories

biblatexnumbering

I have different categories (filters) for entries in a bibliography using
biblatex (see below). I would like to add a numbering to the entries. Since the
entries are sorted by year in decreasing order, the numbering (in each category)
should also be decreasing.

Basically, I see two routes to go:

1) The first is to use style=numeric and a solution presented here.
However, in my (not so minimal) example, there appeared two problems. First, the
number does not start over again for each of the categories (instead, it
continues). Second, I obtained weird numbers (up to 400), although I only had a
couple of entries with the same keyword.

2) The second (probably easier) I found here. This is actually a nice idea (and lets you specify the numbering etc.), but I
couldn't figure out two things: First, how to get decreasing numbering. Second,
if you have > 9 entries, the space reserved for the label is too small and the
10th entry is not vertically aligned with the 9 before. This can probably be
adjusted with itemindent, but when I tried, the adjustments did not have an
effect.

Some more information

1) bibtex as backend is used here on purpose (so that texi2pdf runs biblatex automatically)

2) This problem comes from a CV. The idea is to use \nocite{*} (and not specific \cite{...}s so that I don't have to care about updating the references).

3) In the CV, I show categories "In preparation", "Submitted", "Published", "Book contributions", "Books". I use the following filtering to get this:

\defbibfilter{inpreparation}{type=article and keyword=inpreparation}
\defbibfilter{submitted}{type=article and keyword=submitted}
\defbibfilter{published}{type=article and keyword=published}
\defbibfilter{bookcontrib}{type=incollection and ( keyword=inpreparation or keyword=submitted or keyword=published )}
\defbibfilter{book}{type=book and ( keyword=inpreparation or keyword=submitted or keyword=published )}

Best Answer

The first solution mentioned doesn't work because your bibliography is split by keywords, not by reference sections. The general approach still applies provided that you make the counters keyword-specific.

\AtDataInput{%
  \csnumgdef{entrycount:\strfield{keywords}}{%
    \csuse{entrycount:\strfield{keywords}}+1}}

\DeclareFieldFormat{labelnumber}{\mkbibdesc{#1}}    
\newrobustcmd*{\mkbibdesc}[1]{%
  \number\numexpr\csuse{entrycount:\strfield{keywords}}+1-#1\relax}

This format has a few limitations:

It only applies to keyword filtering, not more general filters defined via \defbibfilter.
The item label width corresponds to \labelnumberwidth. This length is successively increased to accommodate the largest labelnumber based on all entries in the bbl file. So if the keywords filter out many entries, you may find the width too large.

If you don't intend to use the labelnumbers in citations (e.g. entries are accessed only via \nocite), then a simple solution to the above limitations is to patch \printbibligraphy. The following example demonstrates this approach. It also prints entries in the authoryear style.

\documentclass{article}
\usepackage[backend=bibtex,style=authoryear,sorting=ydnt,labelnumber,
  defernumbers]{biblatex}

\defbibfilter{primary}{type=article and keyword=primary}
\defbibfilter{secondary}{keyword=secondary}
\defbibfilter{other}{not type=article and not type=manual and not keyword=secondary}

   \blx@setlabwidth{\labelnumberwidth}{%

[Tex/LaTex] biblatex: Reverse numbering (i.e., count down)

The desired numbering scheme can be achieved by printing the labelnumber as the total number of entries in the current reference section, minus the actual label number, plus one.

This approach is demonstrated in the document below. It relies on commands from etoolbox and allows for an arbitrary number of reference sections.

\documentclass{article}
\usepackage[backend=bibtex,style=numeric,sorting=ydnt]{biblatex}

% Count total number of entries in each refsection
\AtDataInput{%
  \csnumgdef{entrycount:\therefsection}{%
    \csuse{entrycount:\therefsection}+1}}

% Print the labelnumber as the total number of entries in the
% current refsection, minus the actual labelnumber, plus one
\DeclareFieldFormat{labelnumber}{\mkbibdesc{#1}}    
\newrobustcmd*{\mkbibdesc}[1]{%
  \number\numexpr\csuse{entrycount:\therefsection}+1-#1\relax}

\addbibresource[label=biblatex]{biblatex-examples.bib}
\addbibresource[label=base]{xampl.bib}

\begin{document}
\begin{refsection}[biblatex]
  \nocite{markey,companion,ctan,knuth:ct}
  \printbibliography[title={biblatex examples}]
\end{refsection}
\begin{refsection}[base]
  \nocite{whole-set,inbook-minimal,book-minimal}
  \printbibliography[title={Base examples}]
\end{refsection}
\end{document}

If the document is saved as doc.tex, compile with:

latex doc
bibtex doc1-blx
bibtex doc2-blx
latex doc

With backend=biber, there is no need to run biber on each of the reference sections. You can also access bib files remotely from github.

Some caveats:

Shorthands. The labelnumber is overridden by the shorthand field. So with shorthands the maximum labelnumber in a given reference section doesn't correspond to the total number of cited entries. To handle this you can clear the shorthand field with biber by adding the following source map to the preamble:
```
\DeclareSourcemap{
  \maps[datatype=bibtex]{
    \map{\step[fieldset=shorthand,null]}
  }
}
```
Data-only entries. The code in \AtDataInput is executed for each entry in the bbl file. This includes related entries or other entries suppressed in the bibliography via skipbib or dataonly. To omit these from the entry total, you should condition on the skipbib setting.
```
\makeatletter
\def\ifskipbib{\iftoggle{blx@skipbib}}
\makeatother

\AtDataInput{\ifskipbib{}{%
  \csnumgdef{entrycount:\therefsection}{\csuse{entrycount:\therefsection}+1}}}
```
Multiple sorting schemes. If your document uses more than one sorting scheme in a reference section, the bbl file will contain duplicate entries - one for each scheme. To avoid counting duplicates, you can track the entries already counted in a list.
```
\AtDataInput{%
  \xifinlistcs{\thefield{entrykey}}{entrylist:\therefsection}{}{%
    \listcsxadd{entrylist:\therefsection}{\thefield{entrykey}}%
    \csnumgdef{entrycount:\therefsection}{%
      \csuse{entrycount:\therefsection}+1}}}
```
Multiple versus single bib files. Using a single bib file for each reference section is convenient, but not necessary - as long as the entries accessed in each section correspond to those printed in the bibliography. For an alternative approach with a single reference section and labelnumber prefixes, refer to this post.

[Tex/LaTex] Modify bibliography categories

Use the @thesis category and add a type field to specify the type. With \NewBibliographyString you can create the type gethesis (ge: graduate engineer), with \DefineBibliographyStrings you can add/change string definitions for the ngerman language.

\documentclass{article}

\usepackage[ngerman]{babel}

\usepackage[abbreviate=false]{biblatex}

\NewBibliographyString{gethesis}
\DefineBibliographyStrings{ngerman}{%
  mathesis = {Masterarbeit},
  gethesis = {Diplomarbeit},
}

\usepackage{filecontents}

\begin{filecontents}{\jobname.bib}
@thesis{A01,
  author = {Author, A.},
  year = {2001},
  title = {Alpha},
  type = {mathesis},
}
@thesis{B02,
  author = {Buthor, B.},
  year = {2002},
  title = {Bravo},
  type = {gethesis},
}
\end{filecontents}

\addbibresource{\jobname.bib}

\nocite{*}

\begin{document}

\printbibliography
