# Adjustments to bibliography / no comma between author and year / no italic font

I am actually quite happy with the apa style but I need some help to achieve the following two adjustments:

I do not want a comma between the author's name and the year. I don't want italic font at all. It appears for the title of books and for the name of the Journal for articles.

This is my current set up

\usepackage[style=apa]{biblatex}
\DeclareDelimFormat{nameyeardelim}{\space}

\newpage
\pagenumbering{Roman}
\setcounter{page}{3}
\renewcommand*{\mkbibnamefamily}[1]{\textsc{#1}}
\printbibliography

• The biblatex-apa style isn't really designed to be modified because it implements the exact APA styel; you might be better of adapting the authoryear style. But the comma is due to your redefinition of newunitpunct, so you need to explain what you thought you were doing when you added that. You can make titles italic using \DeclareFieldFormat*{title}{\mkbibemph{#1}\isdot}. – Alan Munn Jul 11 at 19:44
• Sorry, that should be \DeclareFieldFormat*{title}{#1\isdot} to remove the italics from titles. – Alan Munn Jul 11 at 20:00

As Alan Munn says in the comments: biblatex-apa is supposed to implement APA style as closely as possible with biblatex. It was not designed with (easy) customisability in mind.

Case in point: Usually you could get rid of the comma between name and year as easily as saying \DeclareDelimFormat[bib]{nameyeardelim}{\addspace}. But biblatex-apa doesn't use this delimiter and uses \newunit\newblock instead, so we need to make it use namyeardelim before we can use it to change the comma.

You can get rid of the italics by redefining the ...title field formats. See for some background Remove Quotation Marks from Style.
