When I read math books, especially in translation, I frequently find errors. Even "minor" errors such as a misplaced minus sign can cost an hour or even a day when it appears in unfamiliar material.

I would like to have a place to record errors that I find in books. Is there any kind of collaborative "clearinghouse" for textbook errors?

    $\begingroup$ It seems that there were some attempts, probably not very useful. You can check the links given in the comments to this question: Math Review - Proposal on area 51. For example: Errata database? (on MO) and Can Matematics S.E. be used to report errors of a text book? $\endgroup$ – Martin Sleziak Jan 28 '19 at 17:21

    $\begingroup$ I'm attempting to keep a list of ring-theoretic errata at my site. If that's the subject area you're interested in, let me know. $\endgroup$ – rschwieb Jan 28 '19 at 18:12

    $\begingroup$ Typically authors have an interest in reports of errata in their published texts. As a search strategy it seems expeditious to query a website that is siloed to mistakes and misprints in a single work (or perhaps the various editions of a work), rather than to have one site within which one tries to identify which works have a particular error. I'd recommend a text which maintains such a website for errata over one that relies on "fans" to sort out its possible mistakes. When an author goes to the trouble of resolving what is or isn't a mistake, one gets a more authoritative resolution. $\endgroup$ – hardmath Jan 29 '19 at 23:09
