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 Bibliography output

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.

author="Briones, Carlos",
bookTitle={\emph{In} {E}ncyclopedia of {A}strobiology},
publisher="Berlin: Springer Heidelberg",

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

    bibliography = {Bibliography},
    references = {Bibliography},

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

\title{Research Paper Step 1}



  • 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

  • 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.

  • 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.

You should use lowercase for the entry types. So to change title and booktitle in inbook do something like this:

\DeclareFieldFormat[inbook]{booktitle}{In \mkbibemph{#1}}

Be aware that the apa style is complicated and that they can be side effects.
