This example shows how to create multiple bibliographies/reference lists in the same document, potentially from different .bib files, using the bibunits package.
For more information, see the bibunits documentation.
This project demonstrates how the xr package can be used on Overleaf to resolve labels in other .tex files that have not been \include-d in the main file.
Make sure you enable the correct system call in latexmkrc, depending on the LaTeX engine you're using!

The purpose of the class yathesis is to facilitate dissertations’ typesetting of theses prepared in France, whatever disciplines and institutes. It implements most notably recommendations from the Ministry of Higher Education and Research and this, transparently to the user. It has also been designed to (optionally) take advantage
of powerful tools available in LaTeX, including packages:
biblatex for the bibliography ;
glossaries for the glossary, list of acronyms and symbols list.
The yathesis class, based on the book class, aims to be both simple to use and, to some extent, (easily) customizable.
