# bibitem symbol change in thebibliography

Using thebibliography environment, I would like to change bibitem symbol. So instead of

[1] Jon Symbolmaster, The Art of Changing bibitem Symbols


there should be e.g.

* Jon Symbolmaster, The Art of Changing bibitem Symbols


or with \blacktriangleright symbol.

I know, it's easy when using beamer with \setbeamertemplate{bibliography item}[triangle] command. But I use baposter and so I'm helpless.

EDIT:

\documentclass[landscape, a0paper, fontscale=0.285]{baposter}

• Can you provide a MWE for us to fiddle with it? – HATEthePLOT Jul 4 '16 at 7:45
• @HATEthePLOT see EDIT – Adela Jul 4 '16 at 8:07

In this case you need to get *, you could add the following macro to your preamble:

\makeatletter
\def\@bibitem#1{\item[*]\if@filesw \immediate\write\@auxout
{\string\bibcite{#1}{\the\value{\@listctr}}}\fi\ignorespaces}
\makeatother


or for getting \blacktriangleright please use the following after adding amssymb package:

\makeatletter
\def\@bibitem#1{\item[$\blacktriangleright$]\if@filesw \immediate\write\@auxout
{\string\bibcite{#1}{\the\value{\@listctr}}}\fi\ignorespaces}
\makeatother


So that the MWE will look like:

\documentclass[landscape, a0paper, fontscale=0.285]{baposter}

\definecolor{yellow}{cmyk}{0,0,0.9,0.0}
\definecolor{reddishyellow}{cmyk}{0,0.22,1.0,0.0}
\definecolor{black}{cmyk}{0,0,0.0,1.0}

\definecolor{lightyellow}{cmyk}{0,0,0.3,0.0}
\definecolor{lighteryellow}{cmyk}{0,0,0.1,0.0}
\definecolor{lighteryellow}{cmyk}{0,0,0.1,0.0}
\definecolor{lightestyellow}{cmyk}{0,0,0.05,0.0}

\makeatletter
\def\@bibitem#1{\item[*]\if@filesw \immediate\write\@auxout
{\string\bibcite{#1}{\the\value{\@listctr}}}\fi\ignorespaces}
\makeatother
