I would have like to know how to reduce the space between each bibliographic reference in a bibliography ? How to not skip a line between each reference ?
I have to respect the following template :
\begin{thebibliography}{}
\policeII
\renewcommand {\baselinestretch}{1.0}
\end{thebibliography}
However, I use Biblatex and I do not know how to take into account the line
"\policeII
\renewcommand {\baselinestretch}{1.0}"
because I deal with my bibliography with these two lines :
\bibliographystyle{ieeetr}
\bibliography{./SFT2020}
Thank you very much for your help.

Bye !
Martin
