# A variation on authoryear (aka “harvard”) citation call-out style [duplicate]

What is the simplest way to make citation call-outs like this:

(Author year: page--range) e.g. (Chomsky 1957: 23--24)

or more complete:

(Author year, volume: page--range; Author2...) e.g. (Knuth 1973, 3: 234--236;...)

Edit: MWE (this is what I have tried):

\documentclass{article}
\usepackage[backend=bibtex,style=authoryear]{biblatex}
\usepackage{filecontents}
\begin{filecontents*}{\jobname.bib}
@book{test,
author = "Author",
title = "Title",
publisher = "Publisher",
series = "Series",
year = 2017,
}
\end{filecontents*}

\bibliography{\jobname}

\begin{document}
word\parencite[345]{test},
word2\parencite{test}
word3\parencite[345--347]{test}
\printbibliography
\end{document}


Edit 2:

It seems as if the two examples above aren't clear enough.

If the the citation is only one book (e.g. if it only one volume) then it should look like:

(Chomsky 1957: 23), if it's a page range (Chomsky 1975: 23--24).

(Without the p or pp prefix.)

If it's more than one book (e.g. if it has multiple volumes) then:

(Knuth 1973, 3: 234), if it's a page range (Knuth 1973, 3: 234--236)

The multiple citations should be separated with ;

• It's almost perfect, only the volume must be before the colon: (Knuth 1986, 2: 345--347) – aksr Apr 30 '17 at 11:14
• That would be inconstistent. – Johannes_B Apr 30 '17 at 11:15
• Maybe, but it's the required style. Only the page number/range should be after the colon and before the optional ; – aksr Apr 30 '17 at 11:18
• @aksr Seems you have a god Minimal Wokring Example to ask a question just about that (required) inconsistency. – Johannes_B Apr 30 '17 at 11:21
• They don't care. I doubt they have heard of LaTeX. – aksr Apr 30 '17 at 11:44
