According to https://apastyle.apa.org/style-grammar-guidelines/references/examples/book-references @book
references should show the publisher
, but not the location
/address
field in APA7 style.
This is exactly what happens if you use an up-to-date version of biblatex-apa
.
\documentclass[american]{article}
\usepackage[T1]{fontenc}
\usepackage{babel}
\usepackage{csquotes}
\usepackage[backend=biber, style=apa]{biblatex}
\begin{filecontents}{\jobname.bib}
@book{elk,
author = {Anne Elk},
title = {A Theory on Brontosauruses},
year = {1972},
publisher = {Monthy \& Co.},
location = {London},
}
\end{filecontents}
\addbibresource{\jobname.bib}
\addbibresource{biblatex-examples.bib}
\begin{document}
Lorem \autocite{sigfridsson,elk}
\printbibliography
\end{document}

If you want 6th edition APA style, where both publisher
and location
are shown, you should load biblatex-apa6
's style=apa6,
\documentclass[american]{article}
\usepackage[T1]{fontenc}
\usepackage{babel}
\usepackage{csquotes}
\usepackage[backend=biber, style=apa6]{biblatex}
\begin{filecontents}{\jobname.bib}
@book{elk,
author = {Anne Elk},
title = {A Theory on Brontosauruses},
year = {1972},
publisher = {Monthy \& Co.},
location = {London},
}
\end{filecontents}
\addbibresource{\jobname.bib}
\addbibresource{biblatex-examples.bib}
\begin{document}
Lorem \autocite{sigfridsson,elk}
\printbibliography
\end{document}

If you absolutely need biblatex-apa
's 7th-edition APA style to show the location (which is not APA compliant), you can try to patch the drivers like this
\documentclass[american]{article}
\usepackage[T1]{fontenc}
\usepackage{babel}
\usepackage{csquotes}
\usepackage[backend=biber, style=apa]{biblatex}
\usepackage{xpatch}
\xpatchbibdriver{book}
{\printlist{publisher}}
{\usebibmacro{location+publisher}}
{}{}
\xpatchbibdriver{inbook}
{\printlist{publisher}}
{\usebibmacro{location+publisher}}
{}{}
\begin{filecontents}{\jobname.bib}
@book{elk,
author = {Anne Elk},
title = {A Theory on Brontosauruses},
year = {1972},
publisher = {Monthy \& Co.},
location = {London},
}
\end{filecontents}
\addbibresource{\jobname.bib}
\addbibresource{biblatex-examples.bib}
\begin{document}
Lorem \autocite{sigfridsson,elk}
\printbibliography
\end{document}
