# How to omit year from biblatex bibliography

I am using a bib file that looks something like this (saved as ref.bib):

@article{key1,
author = {Joe Smith},
journal={A journal},
title = {An article},
year = {2017}}

@article{key2,
author = {Joe Smith},
title = {A second article},
journal = {},
year = {2017},
pubstate={Draft}}


With a latex file:

\documentclass{article}
\usepackage[style=authoryear]{biblatex}

\begin{document}
\section{ONE}
\begin{refsection}
\nocite{key1}
\printbibliography{}
\end{refsection}

\section{TWO}
\begin{refsection}
\nocite{key2}
\printbibliography{}
\end{refsection}
\end{document}


But I would like to omit the year from the second bibliography since it is an unpublished draft. How would I go about doing this?

• Use @unpublished, then year can be omitted. – TeXnician Aug 14 '17 at 16:57
• key2 is definitely not an @article if it has no journal and has not yet been published. There is @unpublished, but also @online if you got the work from a pre-print server. – moewe Aug 14 '17 at 17:00
• Is this for a CV/list of your publications? – moewe Aug 14 '17 at 17:00
• Thanks for the quick responses. Using @unpublished and omitting the year still puts in (n.d.), which I don't want. @moewe - yes, it is for a CV – Alex Aug 14 '17 at 17:02

Use @unpublished and the pubstate field. With

\DeclareLabeldate{%
\field{date}
\field{year}
\field{eventdate}
\field{origdate}
\field{urldate}
\field{pubstate}
\literal{nodate}
}


you get to see the pubstate in the brackets after the author name in the bibliography. To avoid printing the pubstate twice in that case we redefine addendum+pubstate.

This is similar to Andrew's answer in Biblatex: How to get “Author (forthcoming)” when pubstate=forthcoming is set, instead of “Author (n.d.)”?, but ultimately a bit simpler.

MWE

\documentclass{article}
\usepackage[backend=biber,style=authoryear]{biblatex}

\DeclareLabeldate{%
\field{date}
\field{year}
\field{eventdate}
\field{origdate}
\field{urldate}
\field{pubstate}
\literal{nodate}
}

\newunit\newblock
\iffieldequalstr{labeldatesource}{pubstate}
{}
{\printfield{pubstate}}}

\usepackage{filecontents}
\begin{filecontents}{\jobname.bib}
@article{key1,
author  = {Joe Smith},
journal = {A journal},
title   = {An article},
year    = {2017},
}

@unpublished{key2,
author   = {Joe Smith},
title    = {A second article},
pubstate = {draft},
}
\end{filecontents}
