Review article - a special kind of article --- not a research article but a tool for researchers --- valuable for providing a summary of the state of research on a topic for a certain period of time. We expect that the article will receive peer review but will not describe original research. As explained for authors by the American Society of Mechanical Engineers, "A Review Article organizes, clarifies, and summarizes existing major works . . . and provides comprehensive citations to a full spectrum of relevant literature." Note: This is distinct from a systemic review; a systematic review uses the work of previous studies to draw conclusions from all.
The freely available Multilingual Glossary for Today's Library Users - Definitions (from the Instruction Section of the Association of College and Research Libraries division of the American Library Association) is a place to find others definitions for some of these terms, if you would like additional information.
As described by the International Committee of Medical Journal Editors,
"Peer review is the critical assessment of manuscripts submitted to journals by experts who are usually not part of the editorial staff."
Additionally: "Because unbiased, independent, critical assessment is an intrinsic part of all scholarly work, including scientific research, peer review is an important extension of the scientific process."
Sometimes we hear a journal described as "peer reviewed" but papers in the journal are peer reviewed and not the complete journal. Non-peer-reviewed editorials and news updates may appear alongside articles which are themselves reviewed.
For help in determining if a paper has gone through peer review:
Look carefully at the notes with a paper for a description of its progress through the process, often including date received and date finalized for publication.
Check a journal's or conference's website for author information about how papers are reviews.
Use the guidance of library databases which index articles and label them as, for example, "scholarly."
