# Citation brackets using biblatex

I'm using biblatex for references and citations in my thesis.

\usepackage[backend=biber, style=alphabetic, citestyle=authoryear]{biblatex}


gives me the author name in the text, but I would like to have brackets around it. How would I do that?

• \parencite gives you round brackets (parentheses). If you want square brackets a tad more work is needed. Do you really combine style=alphabetic, citestyle=authoryear,? If there is no other code to combine these two styles the output will be a bit odd. – moewe Mar 18 at 10:16

With (cite)style=authoryear \parencite gives you round brackets (parentheses) by default. It is possible to switch to square brackets as shown in Biblatex, author-year, square brackets. If you use biblatex-ext it is slightly more comfortable to do that with the command \DeclareOuterCiteDelims.

\documentclass[british]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{babel}
\usepackage{csquotes}

\usepackage[style=ext-authoryear, backend=biber]{biblatex}

\DeclareOuterCiteDelims{parencite}{\bibopenbracket}{\bibclosebracket}
