Do you mean for review, or even when they&#x27;ve accepted and ask for a camera-ready version?  I always assumed all publishers need the source so they can do the small tweaks they do.<p>[OTOH, I&#x27;ve seen claims many publishers already have a process for publishing Word submissions — something involving monks spending their lives typesetting everything from scratch? — and so when they do get a nice LaTeX, they throw the source out re-use the above process!  Perhaps that was only about the bibliography though.]<p>I&#x27;ve seen some Springer (LNCS) submissions, and those definitely included the .tex source.<p>arXiv requires the source, mainly so they can re-compile them in the future with better tools [<a href="https:&#x2F;&#x2F;arxiv.org&#x2F;help&#x2F;faq&#x2F;whytex" rel="nofollow">https:&#x2F;&#x2F;arxiv.org&#x2F;help&#x2F;faq&#x2F;whytex</a>].  Unusually, they make sources available for anyone to download.
