Deactivate oldstyle figures in the bibliography

Question

I use oldstyle figures in the body text and also for the references. In the bibliography, however, the years, editions, volumes and issues do not look good as OSF. How can I deactivate these for the bibliography? Please have a look at the MWE, this is about "1972".

\begin{filecontents}{\jobname.bib}
    @book{Labov1972,
        Address = {Philadelphia},
        Author = {William Labov},
        Publisher = {University of Pennsylvania Press},
        Title = {Sociolinguistic Patterns},
        Year = {1972}}
\end{filecontents}
\documentclass[a4paper,11pt]{article}
\usepackage[style=numeric,backend=biber]{biblatex}
\addbibresource{\jobname.bib}
\usepackage[osf]{mathpazo}
\begin{document}
    Example citation \cite{Labov1972}. 
    \printbibliography
\end{document}

\renewcommand\rmdefault{ppl} before the bibliography will change all numbers. If you need more specific changes you will have to add that to the various biblatex field formats. — Ulrike Fischer, Mar 22 '24 at 15:21
Thank you for your answer. Do you have an example of this? In particular, I would like to achieve that only the title information is written with upright numbers and not the references [1], [2], etc. as well. — Sargos, Mar 22 '24 at 15:36

Indeed (as mentioned by Ulrike in a comment) switching to ppl (Palatino with regular numbers) will help. You can do that by redefining \rmdefault, but another option is to redefine \bibfont as in Biblatex: Changing the font of citation-marks and the references?.

In order to keep the oldstyle figures for the citation label you can locally change back to pplj inside the BibLaTeX field labelnumberwidth which formats the citation label, as in Removing brackets from biblatex references for lncs.

\begin{filecontents}{\jobname.bib}
    @book{Labov1972,
        Address = {Philadelphia},
        Author = {William Labov},
        Publisher = {University of Pennsylvania Press},
        Title = {Sociolinguistic Patterns},
        Year = {1972}}
\end{filecontents}
\documentclass[a4paper,11pt]{article}
\usepackage[style=numeric,backend=biber]{biblatex}
\usepackage[osf]{mathpazo}
\renewcommand*{\bibfont}{\fontfamily{ppl}\selectfont}
\DeclareFieldFormat{labelnumberwidth}{\fontfamily{pplj}\selectfont[#1]}
\addbibresource{\jobname.bib}
\begin{document}
Example citation \cite{Labov1972}. Old-style figures in numbers: 1972, [1].
Comparison with mathpazo in text and ppl in bibliography:\[1cm]
\normalfont\frenchspacing
\noindent[1]\quad William Labov. \textit{Sociolinguistic Patterns.} Philadelphia: University of Pennsylvania Press, 1972.
\printbibliography
\end{document}

Result:

Works great. As always, I am very impressed by your expertise and helpfulness. — Sargos, Mar 23 '24 at 12:53
