# Remove dot after entry title in Biblatex

My teacher has a very specific way he wants bibliographies to be done which is similar to APA, but with changes. To fully comply with what he wants, I need to remove the dot that is automatically inserted after the entry title in a @Inbook item. I am using the biblatex-apa style as it is already very close to what I need.

For example, I would like to get

Briones, C. (2014). Quasispecies In Encyclopedia of Astrobiology. Berlin: Springer Heidelberg.

As the output of in my bibliography. What I get using my entry linked bellow is

I guess I have to use \DeclareFieldFormat, but I don't seem to be able to get it to work since even just trying to add text to it like such: \DeclareFieldFormat[Inbook]{title}{Title: \mkbibemph{#1}} does nothing.

This is my entry in my .bib. I know I used some hacks like adding the "In" to the bookTitle entry, but it was the simplest way I could find to get what I needed.

@Inbook{Briones2014Quasispecies,
author="Briones, Carlos",
title={Quasispecies},
bookTitle={\emph{In} {E}ncyclopedia of {A}strobiology},
year="2014",
publisher="Berlin: Springer Heidelberg",
}


M(N)WE: (Using the bib entry given earlier)

\documentclass[11pt]{article}
\usepackage[style=apa]{biblatex}
\DefineBibliographyStrings{english}{%
bibliography = {Bibliography},
references = {Bibliography},
}

%Does not change anything to output:
\DeclareFieldFormat[Inbook]{title}{Title: \mkbibemph{#1}}

\author{Natmath}
\date{\today}
\title{Research Paper Step 1}

\begin{document}

\maketitle

\cite{Briones2014Quasispecies}

\printbibliography

\end{document}


• show a small but complete example, that makes it much easier to test your issue. Mar 26 '21 at 18:38
• Ok, I added and example with the citation, style and entry. @UlrikeFischer, thanks Mar 26 '21 at 18:46
• you need to use lowercase for the entry types, so something like this \DeclareFieldFormat[inbook]{title}{\mkbibemph{#1}\nopunct}\DeclareFieldFormat[inbook]{booktitle}{In \mkbibemph{#1}}, but be aware that apa is complicated and imho it is better to leave it as it is. Mar 26 '21 at 19:16
• Thank you very much, this works. Would you mind writing it as an answer, and I'll accept it for further reference to others. Mar 26 '21 at 21:24
• I know that this breaks APA standards, but I kinda have to do it because this teacher is super strict on his own variation of APA. Thank you still. Mar 26 '21 at 21:24

\DeclareFieldFormat[inbook]{title}{\mkbibemph{#1}\nopunct}
