AI Thread Summary
The discussion centers around managing references in a LaTeX document divided into multiple chapters. The user seeks a method to ensure that each chapter only references its own equations, sections, and figures, avoiding label conflicts. Suggestions include generating separate PDFs for each chapter and then combining them, as well as changing labels to include unique prefixes to prevent duplication. However, concerns are raised about the challenges this poses when chapters reference each other or share a bibliography. Ultimately, the user decides to rename the equations to resolve the issue, acknowledging the simplicity of this solution despite initially seeking a package to simplify the process.

Hi PF!

I have a divided a main.tex into chapters, chapter_1.tex, chapter_2.tex... Each chapter is included in the main.tex via \include{chapter_1}. Each chapter also references equations. Is there a way to have each of the chapter_1.tex only reference that file's equations, sections, figures? As is, I have multiple defined labels.

Thanks so much!

Why don't you generate the pdf for each chapter separately, and then combine them into one file? This would be better than including all those chapters into the main .tex file. Adobe online, for instance, allows you to combine files for free.
 
Why not simply change the labels? Each file/chapter could have its own label prefix to make sure there can be no multiply defined labels (it is easy to perform a search and replace in each file to include those prefixes).

That breaks things if one chapter makes references to the content of another, or you have page references, or you want to generate a single bibliography for the entire work.

The sad and somewhat dry truth is to not use the same label several times in different files if you want to compile them together. Making references between the files is a feature and this requires unique lables. I suggest going with #3.

Thanks everyone. I'll just rename the equations. Wasn't sure if there was a package available that made this simple, but this is still very easy.
