This Answer shows how to use a user-defined icon when using the thebibliography environment. How can I redefine the icons if I use \printbibliography from biblatex?
Edit:
In the answer I linked to, each bibliography item is set manually, and so you can add
\setbeamertemplate{bibliography item}{\includegraphics[width=1.5em]{ctanlion}}
\bibitem{A} CTAN lion drawing by Duane Bibby.
in front of each seperate entry if you wanted to. With \printbibliography the whole bibliography is typeset. So if I were to say
\setbeamertemplate{bibliography item}{\includegraphics[width=1.5em]{ctanlion}}
\printbibliography
it would appear in front of the bibliography as a whole, not even in front of the first entry.
biblatexwhich item gets which icon? – moewe Feb 19 '16 at 15:13biblatexwhich icon to pick for which entry. In the second answer for example you can simply replace the\setbeamertemplate{bibliography item}[online]bits by\setbeamertemplate{bibliography item}{\includegraphics[width=1.5em]{ctanlion}}to get your custom icon for@onlineentries. But you could also make sure that not the type but akeyworddecides which icon to use. ... There are quite some ways to do that. What did you have in mind? – moewe Feb 19 '16 at 15:50.bibentries. This will not only make it easier to help you, it will also make it more likely that the help you receive will actually be useful. – cfr Feb 20 '16 at 03:18
