Every textbook has errors. Let’s keep track of them — carefully.
A community-maintained record of errors in mathematical textbooks: reported, discussed in LaTeX, and verified — edition by edition.

A report is a question, not a verdict
One reader saying “this proof is wrong” does not make it wrong. Every issue shows how much is actually known, and every status change is explained in public.
- Reported
Someone thinks there may be a problem. Not yet discussed — this is a question, not a verdict.
- Under discussion
Other readers are investigating whether this is really an error.
- Confirmed error
The community investigated and established that the book is wrong here.
- Author-confirmed
The author or publisher has confirmed the error (directly, or in official errata).
- Not an error
Investigated: the book is correct here (or the report was withdrawn).
Each issue also records which editions contain it, so you can see what affects your copy. More about statuses
