File first.tex
\documentclass{article}
\begin{document}
This interesting book \cite{book}.
\begin{thebibliography}{10}
\bibitem{book}

\documentclass{article}
\usepackage{xr}
\externaldocument{first}
\begin{document}
Please read \cite{book2}.
\end{document}If you want to refer some label that exist in a tex document named first.tex, in a separate document named second.tex, you can use the xr package,
in the second.tex file put,
\usepackage{xr}
\externaldocument{first}Now you can refer some lable in the first.tex file in the usual \ref command. You can also use a prefix to differentiate between the lable in first and second document
\externaldocument[I-]{chapterI}Now to refer some lable fig1 in the first.tex, use \ref{I-fig1} in the second document.
- For online latex editor like Overleaf the process, you have to do few extra step, see here https://www.overleaf.com/learn/how-to/Cross_referencing_with_the_xr_package_in_Overleaf .
- My suggestion: This process works, but if you have to share one tex file as a standalone document, then things gets messed up. In that case, it is better to define the lable you want to refer as a latex variable, like
\newcommand{\figone}{1}and refer them with the\figone{}command.
Use the pgffor package
\foreach \n in {1,2,3,4,5}{
Current number is \n
}\NewDocumentCommand{\parencite}{m}{\begingroup\bibpunct{}{}{,}{n}{}{,}\cite{#1}\endgroup}
