Peer Review Process
Peer review exists to ensure that journals publish good science that benefits the entire scientific community.
Sometimes authors find the peer-review process intimidating because it can lead to the rejection of their manuscript. Keep in mind that revisions and improvement are part of the publication process and actually help raise the quality of your manuscript.
A question often asked by authors, but also important to editors, is how long does it take between submission and publication of an article. This is a hard question to answer, but often peer review is the lengthiest part of this process. Journals usually ask reviewers to complete their reviews within 3-4 weeks.
