Biblatex provides several standard citations styles, if no citation style is set LaTeX uses the one that matches the bibliography style. Below you can see an example:



\addbibresource{sample.bib} %Imports bibliography file

\section{First section}

This document is an example, two items are cited: \textit{The \LaTeX\ Companion} book 
is \cite{latexcompanion}, and Einstein's journal paper is \cite{einstein}.




The parameter citestyle=authoryear passed to the command that imports biblatex is the one that sets the citation style, in this case authoryear. The standard citation styles are:

  • numeric Implements a numeric citation scheme intended for in-text citations. Should be employed in conjunction with the numeric bibliography style.
  • numeric-comp Compact variant of the numeric mode. Citations like [1, 2, 3] are replaced by [1-3].
  • numeric-verb Verbose variant of the numeric style. Instead of [2, 5, 7] will print [2];[5];[7].
  • alphabetic Alphabetic citation scheme similar to the standard alpha in style bibtex. To be used in conjunction with the alphabetic bibliography style.
  • alphabetic-verb Verbose version of the alphabetic style. Instead of [Doe98, Doe95, Farn2004] will print [Doe98];[Doe95];[Farn2004].
  • authoryear Implements the author-year citation scheme. To be used in conjunction with the author-year bibliography style.
  • authoryear-comp Compact variant of the authoryear style. Prints the author only once if subsequent references passed to a single citation command share the same author. Prints Doe 1992, 1995 instead of Doe 1992, Doe 1995.
  • authoryear-ibid A variant of the authoryear intended for footnote citations. Replaces repeated citations by the abbreviation ibidem.
  • authoryear-icomp A style combining the features of authoryear-comp and authoryear-ibid
  • authortitle Implements the author-title scheme. Intended for citations given in footnotes.
  • authortitle-comp Compact variant of authortitle. Instead of Doe, First title; Doe, Second title this will print Doe, First title, Second title.
  • authortitle-ibid A variant of the authortitle intended for footnote citations. Replaces repeated citations by the abbreviation ibidem.
  • authortitle-icomp A style combining authortitle-comp and authortitle-ibid.
  • authortitle-terse Variant of authoritle that only prints the title if the bibliography contains more than one work of the respective author/editor.
  • authortitle-tcomp Style combining authortitle-terse and authortitle-comp.
  • authortitle-ticomp Style combining authortitle-icomp and authortitle-terse.
  • verbose Citation style that prints a full citation when the entry is cited for the first time and a short version afterwards.
  • reading Citation style that goes with the bibliography style by the same name. Loads the authortitle style.
