When I start reading a paper, is there some easy way to find a list of corrections for that paper?
For example, it happens occasionally that some result of a paper turns out to be wrong, or at least that the proof is incorrect and not salvageable, and I might not myself easily be able to spot the error (it will after all have been missed by both the original author(s) as well as the reviewers of the paper). And in such a situation, I would hate to end up using such a result in a crucial way only to later discover that it was not correct.
Another thing is that I might have been working on something similar which turns out to be a special case of such a result. In that case, if I am not aware that the proof (or possibly even the stronger result) is incorrect, I might stop working on that particular problem, even if I felt close to a solution, believing that it had already been settled.
In these cases, it would be nice to have some centralized list, where I could find the paper and see if it has had any corrections.
(I had a hard time figuring out what to tag this question, so please feel free to change the tags).
