# [Tex/LaTex] Short harvard citation

biblatexharvard-style

I need to cite the following way:

The first 3 Letters of the author + the year.

Example:

Kemper 2009 –> [Kem09]

But I don't have any clue how to do that!

This is the standard with biblatex’s style alphabetic, as long as you have one author. With multiple authors, this style takes the first letter of every author – up to three, as a default. If there are more than three authors, it takes the first three letters of the first name, then a + and the year, e.g.

Kemper 2009 > [Kem09]

Goossens, Mittelbach and Samarin 1994 > [GSM94]

Kemper et al. 2011 > [Kem+11]

Edit:

As Audrey stated in the comments, you can change the name of the authors that are used for the alphabetic label with the option maxalphanames. With maxalphanames=1, the above examples would look like this:

Kemper 2009 > [Kem09]

Goossens, Mittelbach and Samarin 1994 > [Goo+94]

Kemper et al. 2011 > [Kem+11]

If you want to get rid of the +, you can redefine the \labelalphaothers command: \renewcommand*{\labelalphaothers}{}
