The content of refereed publications is sanctioned, vetted, or otherwise approved by a peer-review or editorial board. The peer-review and evaluation system is utilized to protect, maintain, and raise the quality of scholarly material published in serials. Publications subject to the referee process are assumed, then, to contain higher quality content than those that aren't.
A thorough review with emphasis on novelty and soundness. The refereeing process seeks to advise the editor whether to reject or provide specific guidance for revisions prior to acceptance by the editor. Persons serving as referees are independent of the editors who request their advice.
