I am working on a document which necessitates a creation of two bibliographies: one which lists further reading materials and another containing the bibliographic entries of all in-text citations.

I currently use biblatex keywords to do so. However, I need for the same reference (smith15 in the following MWE) to show up in both bibliographies. How can I achieve such result?

citations.bib

@book{doe14,
  author = {John Doe},
  title = {Sample Title},
  date = 2014,
  publisher = {Sample Publisher},
}

@book{smith15,
  author = {Jane Smith},
  title = {Sample Title},
  date = 2015,
  publisher = {Sample Publisher},
  keywords = {custom},
}


@book{johnson16,
  author = {Steve Johnson},
  title = {Sample Title},
  date = 2016,
  publisher = {Sample Publisher},
}

main.tex

\documentclass{article}

\usepackage[style=apa]{biblatex}
\addbibresource{citations.bib}


\begin{document}


% Main Text
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Morbi pretium dictum efficitur \parencite{doe14, smith15, johnson16}.


% Custom Bibliography
\nocite{smith15}


\printbibliography[keyword={custom}, title={Custom Bibliography}]


\printbibliography[notkeyword={custom}]


\end{document}

Current Output

1

Expected Output

smith15 should appear in both bibliographies.

    Do you want something like https://tex.stackexchange.com/q/6967/35864? – moewe Mar 25 '24 at 07:23

    In this example it is clear that smith15 won't be shown in the second bibliography, because the code specifically asks the bibliography to ignore all entries with the keyword custom, which smith15 has set. So you need a better way of telling LaTeX which entry to print where. This suggests that keywords are not the right course of action here. – moewe Mar 25 '24 at 07:25
  • @moewe, thank you for linking that thread. For now, I used category={cited} for the main bibliography and keyword={custom} for the custom bibliography; now smith15 appears in both. I'm not sure whether there is a cleaner solution so I left this as a comment instead of an answer. – Einreinfall Mar 25 '24 at 09:19
  • The best solution depends on your exact use case and expectations. If you want all cited entries to go into one bibliography and only ever \nocite those entries that go into the other list, then I think https://tex.stackexchange.com/q/6967/35864 is the cleanest solution and you won't even need keywords. If you have something more complex in mind, then you might need something more sophisticated. At least in the example and from what I understand so far I don't see the need for keyword = {custom}, and think the linked solution would be enough - but there may be reasons for using it. – moewe Mar 26 '24 at 07:03
