Peer review is a central concept for most academic publishing; other scholars in a field must find a work sufficiently high in quality for it to merit publication. A secondary benefit of the process is an indirect guard against plagiarism since reviewers are usually familiar with the sources consulted by the author(s). The origins of routine peer review for submissions dates to 1752 when the Royal Society of London took over official responsibility for "Philosophical Transactions." However, there were some earlier examples.
