The issues surrounding how to use latex for submitting an article to a journal (eg, how to deal with disallowed packages, journals with postscript-only workflows, bundling files together for submission) and how to use latex to publish a journal issue (eg, how to combine possibly conflicting from multiple submissions, how to extract metadata and abstracts, how to generate PDF/X or PDF/A, font licensing and embedding for publication, etc) are pretty distinct. Self-publishing a book is different again (eg, which print-on-demand printers will accept latex-generated pdf, how to deal with bleeds and colour profiles and page imposition and such). Placing a TeX manuscript into a traditional publishing workflow is different again (I have no experience, but things like dealing with copyeditors, indexing professionals, book designers). I think publishing is too vague and could be broken down into {self-publishing} etc, and journal could be more obvious like {journal-submission}.
