# Referencing earlier passages: Cross reference or “as discussed earlier”

I am looking for stylistic advice regarding the (over) use of cross-references. For instance, using cross-references in Latex through \ref{...} for major structural blocks like chapters and sections certainly is a good idea. But when it comes to subsections or subsubsection that are only one or two pages long, technical cross-references begin to feel a little over the top and I prefer using phrases such like as mentioned earlier or as discussed in the previous section (while possibly actually meaning a latex subsubsection). I also prefer it this way, as I don't like numbered headings for subsections and subsubsections, for the same reason: It looks overkill. But numbered headings are requiered for the cross-references to work.

So, should I rather use technical cross-references with \ref{...} throughout the text? Are the more or less agreed upon stylistic rules for this in scientific writing?

• "But numbered headings are required for the cross-references to work." I think there should be a way to attach the link to a word other than the section number; not helpful for the printed version, but would to the trick for the pdf. Also it depends a lot on how your manuscript reads. The more your sub(sub(..))sections can be read independently, the more you need detailed cross references IMO because you can less assume that the reader has seen the previous material – EigenDavid Jul 15 '19 at 10:22
