Reprints
Publication of manuscripts in a peer-reviewed journal often takes weeks, months, or even years from the time of initial submission, owing to the time required by editors and reviewers to evaluate and critique manuscripts, and the time required by authors to address critiques. The need to quickly circulate current results within a scholarly community has led researchers to distribute documents known as preprints, which are manuscripts that have yet to undergo peer review. The immediate distribution of preprints allows authors to receive early feedback from their peers, which may be helpful in revising and preparing articles for submission
