I'm working with Latex for the first time, so I don't quite understand the syntax of the bibliography styels.
For my thesis I need the citation to be 4 letters of author name/names and 2 numbers for year. For one author Mustermann [Must14], two autors [MuAn14], 3 authors [MuAB14]
The closest style I found was alpha. But it only shows 3 letters. Is there a way to easily modify it?
