> how to check if an article was peer reviewed or had harsh response from academic sources. This is a different problem than the issue of a central repository for all peer reviewed articles. Some journals allow you to see the trail of the actual peer review (questions raised by reviewers, responses & changes made by authors, etc) but this is far from the norm. The standard practice is to only offer the final version of the article, and to not release the trail of peer review to the general public. pubpeer.com does allow people to raise concerns and discuss individual publications for technical issues/plagarism, and its typical for the authors to come on there and provide further information or clarifications. Pubpeer however is a third party site distinct from the peer review process that journals do before publication. It's also not uncommon to see papers pulled due to concerns raised on pubpeer.
