Academic papers keep getting longer, to the point where these days, we rarely read a paper as opposed to leafing through it for highlights. Here’s an extreme example that has caught my eye today. There’s a trio of numerical analysts who have published 39 papers together since 2003, with these statistics at Google Scholar:
Average number of pages: 40.9, Total pages: 1594.
Average number of citations: 27.8, Total citations: 1084.
These are good people employed at good universities, and the papers are in the top journals. Yet I regard these numbers with horror. In my career, I’ve published five papers longer than 30 pages. These guys have 29 of them! When I look at the latest, with its 278 lines of displayed equations, my eyes glaze over.
I am certain that the mountain of long technical papers out there is bad for communication. The disturbing question is, is it good for careers? I hope no, but I fear yes. I have tried to push back against the trend in conversations with colleagues, as a referee and journal editor, in a letter printed in SIAM News, and indeed as SIAM President, but I don’t recall encountering anybody who agrees with me that this is something we should be exercised about.

I agree. As the famous quotes go, “less is more” and https://quoteinvestigator.com/2012/04/28/shorter-letter/ (Pascal).
