# Citation style with first letters of author's lastname

I'm searching for a citation style. Im using biblatex and I want the following citation using the first letters of the last name and the year of publishing:

For only one author the referance should consider the first three letters and the year like: [Lot08] for the name Loth and the year 2008.

For more than one auther the referance should look like this [BMCW12] which contains the first letters of the lastname of the authors (Becker, Meier, Conrady, Wolf) and the year. I know this is very similar to the alphabetic style but I don't want to get the plus inside the cite like [BMC+12]. In addition I want to fix the number of letters to 4 even if there are more authors.

Is there such a citation style available or do I have to adjust the alphabetic style??

Thank You

• Have you looked at the package biblatex-trad that emulates the abbrev style? – Denis Feb 23 '16 at 11:55

You can customise the alphabetic label style quite heavily with \DeclareLabelalphaTemplate (see §4.5.4 Labels, pp. 163-169 of the biblatex manual). In your case that is not necessary, however.

You only need the add the two options

maxalphanames=4, minalphanames=4

to your biblatex call to get the number of names as desired.

And then

\renewcommand*{\labelalphaothers}{}

gets rid of the "+" that shows that authors have been omitted.

MWE

\documentclass[a4paper,10pt]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[style=alphabetic,maxalphanames=4,minalphanames=4]{biblatex}
