# BibLaTeX, how to customize authortitle style?

really really new to LaTeX, I must admit.

I was wondering if is it possible to customize a biblatex style since I looked and looked but none matches the one required by my university.

Briefly (an @article here as an example)

this is what I get with authortitle: Smith, J. “Article Title”. In:Journal Name(1999), pp. 1-10

this is what I need: J. Smith, Article Title in Journal Name, 1999, pp. 1-10

To sum up the differences: No quotation marks, no parentheses, no colon and possibly inverted order in the name.

• Hi, welcome to TeX.SE! This is possible, yes, but (in my admittedly limited) experience often difficult. My suggestion would be to find a style that closely matches what your university requires, and then inquire whether using that one would be acceptable. In my experience, many professors don't mind. Generally, also see tex.stackexchange.com/q/67248/158639 , BTW.

One example of one particular @article entry is by far not enough to implement a complete bibliography style with biblatex, but the following can be a start.

The code is based on ext-authortitle from my biblatex-ext bundle (because that makes a few modifications easier). Most commands below should have fairly self-explanatory names (you can also look up most things in the biblatex documentation or the biblatex-ext documentation), but I'll be happy to answer any questions in the comments.

\documentclass[british]{article}
\usepackage[T1]{fontenc}
\usepackage{babel}
\usepackage{csquotes}

\usepackage[
backend=biber,
style=ext-authortitle,
giveninits,
uniquename=init
]{biblatex}

\DeclareNameAlias{sortname}{default}

\DeclareFieldFormat*{title}{\mkbibemph{#1}}

\renewbibmacro*{in:}{%
\bibstring{in}%
\printunit{\intitlepunct}}
