MathOverflow is a question and answer site for professional mathematicians. It's 100% free, no registration required.

Some authors do a really great job by collecting errors and comments to their books and putting a list on their websites. I wonder if there is some (perhaps wiki-style) website where errata are collected. Does anybody know?

There isn't. This was proposed a few weeks back on the algebraic-topology mailing list. In response to that, a forum was started to discuss this idea, called the r-forum. Contributions are welcome.

Seeing the 7 upvotes on this post, I am somewhat disappointed when I navigated to the r-forum and found it completely empty. –  Willie Wong Feb 5 '14 at 15:59
@WillieWong This was posted in 2009. It is now 2014. At some point in those five years, the rForum ceased operation. At a later point, I migrated all of the forums that I ran, but obviously the rForum didn't migrate properly and no-one's noticed until now! The old posts are still around - I haven't deleted the database. If I get a minute I'll figure out what went wrong with the migration. –  Loop Space Feb 9 '14 at 19:23
** grumble non persistent links grumble ** Glad I could be of service. :-) Offhand do you remember there being any interesting conclusions in that discussion? If there weren't any, then there's little point reviving the link... –  Willie Wong Feb 11 '14 at 8:56
** grumble only me who seems to do this stuff grumble ** I think that there was some discussion that would be useful to have archived. I'll dig it out and get it visible again. –  Loop Space Feb 11 '14 at 17:28

Not quite what you asked for...but useful anyway: Mathematical Errata

There are a lot more errata than that on the web, though. –  Michael Lugo Oct 28 '09 at 14:45
This link no longer works. –  Marius Kempe Sep 17 '14 at 19:00
It's too bad this went away. You can still see it in web archives like the WayBack Machine. But the last update was 2007. A reason that errata lists should be in permanent places. –  Gerald Edgar Sep 17 '14 at 19:22

I think not only for books, but for published papers etc. also there should be errata lists----these could really save many a hair-pulling moment! Moreover, this will make the errata-fixing process public, and because of that probably faster and more transparent.

In fact, it would be great if such a database were created on the stackexchange.com framework, because that works so admirably for MO.

I created a proposal on stackexchange.com, if you are interested please follow it here:


Additionally, if someone has a better proposal, I am totally willing to support that too.

Man, I'm really going back and forth on this one. On the one hand, a StackExchange/MathReviews/arXiv/"errata-base" hybrid site sounds awesome. On the other hand, how would that even work? –  Ross Churchley Nov 12 '10 at 1:48
Yeah, I myself have been vacillating for more than a month; yesterday a colleague of mine expressed strong interest in such a site, which impelled me to write this response. I think, because making errata lists is soooo boring (at least for me), such a stackexchange might not be sustainable....especially because the original authors might be either dead, or somehow otherwise indisposed to responding. Hmmm.. –  Suvrit Nov 12 '10 at 9:55
