I'm wanting to merge three .tex files together in a way that allows the formatting of each file to remain the same. So I want each file to show in the exact same way as they show when I view them individually.
I've tried using functions such as \input, \include and \pdfpages. But they all seem to change the section numbers, section heading sizes and other aspects.
I've tried downloading each .tex file as a pdf, then including the pdf version in the main .tex file, but it still changes the section numbers, etc.
I'm wanting to have one main file so that I can then add page numbers for the whole thing.
\end{document}not to end the process, and moreover disable page numbering in the remaining documents. You would have to deal somehow with identical labels in different documents and many more things. – gernot Nov 21 '20 at 18:25pdfpages? See e.g. https://tex.stackexchange.com/q/77751/110998 – gernot Nov 21 '20 at 18:27pdfpages, because it does not change section numbers or font size. – Andreas Matthias Nov 23 '20 at 16:14
