Every reputed publisher becomes big because of the quality of the manuscripts they are able to maintain in the long run. The peerreviewing process is the backbone of the publishing industry, which helps maintain the quality and authenticity of the research a journal publishes. Peer reviewers are usually the scientists and faculty working in academic and research institutions. When a journal receives a manuscript, they do a technical check on the manuscript and forward it to reviewers for peer review. Reviewers receive an email from a journal requesting peer review, and the reviewer has to decide whether to accept or reject the review request of the journal. If the reviewer accepts the review invitation, the journal gives a few weeks to the reviewer to read and comment on the manuscript; if the reviewer rejects the invitation, the peer review request is forwarded to another reviewer by the journal. The process is thus going on till a reviewer accepts the invitation.
