Synchronizing bibliography labels accross refsections

Question

For my dissertation I have the requirement that all of my own articles that are cited in the text are included in the general references section and all of my own articles are included in an extra references section. I'm using biblatex. To collect all of my paper in the extra section I use keyword filtering in combination with \nocite{*}. To prevent the \nocite{*} to propagate to the general references, I use a “refsection”. That works perfect except that the labels are not synchronized. How can I synchronize the labels? What would be the correct approach to achieve what I have to fulfill?

The following code/picture illustrates the problem:

\documentclass{scrartcl}

\begin{filecontents}{testbib.bib}
@Article{MyArticleA,
  Title                    = {Article A},
  Author                   = {Me},
  Journal                  = {Nature},
  Year                     = {2015},
  Number                   = {13},
  Pages                    = {156},
}
@Article{MyArticleB,
  Title                    = {Article B},
  Author                   = {Me},
  Journal                  = {Nature},
  Year                     = {2015},
  Number                   = {14},
  Pages                    = {228},
}
@Article{MyArticleC,
  Title                    = {Article C},
  Author                   = {Me},
  Journal                  = {Nature},
  Year                     = {2015},
  Number                   = {15},
  Pages                    = {111},
}
\end{filecontents}

\usepackage[style=alphabetic]{biblatex}
\bibliography{testbib}

\begin{document}

\noindent Citation of Article B: \cite{MyArticleB}; Citation of Article C: \cite{MyArticleC}

\printbibliography

\begin{refsection}
\nocite{*}
\printbibliography[title={My Publications}]
\end{refsection}

\end{document}

Answer 1

Since refsections are kept completely independent and separate of each other, there is no easy way of making the labels align between two different refsections. Sometimes using refsegments, which are not kept separate, can help solve the problem. In the case at hand, though, refsegments will not do what we want.

In order to keep the \nocite{*}, we need to be able to distinguish works that were really (i.e. visibly) \cited from those added only via \nocite. A easy solution for this is explained in How to split bibliography into “works cited” and “works not cited”?

\DeclareBibliographyCategory{cited}
\AtEveryCitekey{\addtocategory{cited}{\thefield{entrykey}}}

In your MWE that will already be enough, but maybe we also need a way to filter only your publications. You can get inspired by biblatex: filter out publications from a specific author in the references dynamically, biblatex: separating publications of a specific author in the bibliography, How to print a bibliography for a particular author only?. The solution here is based on the fullhash calculated by Biber, it can identify names as uniquely as Biber allows for

\defbibcheck{mywork}{%
  \iffieldequalstr{fullhash}{e06f6e5a8c1d5204dea326aa5f4f8d17}
    {}
    {\skipentry}
}

If you use different formats/versions of your name, for example "A. Uthor", "Anne Uthor" and "Anne K. Uthor" you will have to account for all of these. You can find the namehash generated for a name in the .bbl file. For example

\defbibcheck{mywork}{%
  \ifboolexpr{test {\iffieldequalstr{fullhash}{e06f6e5a8c1d5204dea326aa5f4f8d17}} or test {\iffieldequalstr{fullhash}{fb328aaf7bc297844ac66ad9e0844e1b}}}
    {}
    {\skipentry}
}

will classify both "Anne Uthor" as well as "Anne K. Uthor" as your publication.

Now the "normal" bibliography is

\printbibliography[category=cited]

and your list of publications is

\nocite{*}
\printbibliography[title={My Publications},check=mywork]

Where of course the actual position of \nocite{*} in your document does not really matter.

\printbibliography[category=cited]

\nocite{*}

\end{document}

Even though MyArticleD is in the .bib file it does not appear in either of the lists, because it is neither one of your (viz. Anne Uthor's) publications nor one of the works cited.
