Books with errors are quite dangerous and would be very helpful find the errors of a book and report and discuss them in some place where everyone can check if the books he is reading has errors and correct them before struggling with them. Can we use Mathematics S.E. for this reason? Can I post a question, (community question?) like this: - Errors in "A Book of Abstract Algebra" by Charles C. Pinter - and leave it open so every one who thinks to have find an error post it as an answer and the community can check is if a true error. I think this could be very helpful... And it can save a lot of time and errors!
Edit
I think the answers would be more accessible, this would not an invasion of questions about errors in textbook but simply a way to organize better this sort of questions when they comes, so if someone ask for a possible error in a book the question can be joined as an answer to the related community question even if it is created at the moment. Many questions can be placed in a single question more accessible for further users.
Please if you downvote tell me the reason of the downvote, what does it means, I write it in a wrong way? Is a duplicate? Too obvious?
