DrugMonkey wonders about the ethics of reviewing a manuscript that you've already reviewed for another journal. The post says it's OK to accept these articles for review, but wonders if reviewers have an obligation to tell the editor that the article has already been rejected by another journal. "As an author, I think that on the whole I would prefer that the editor be informed when a reviewer has seen the paper before. As a reviewer all I can say is that I do generally indicate this to the editor," writes DrugMonkey.
