Wikipedia:Peer review

Peer reviews are open to any feedback, and nominators may also request subject-specific feedback. Editors and nominators may both edit articles during the discussion. Compared to the real-world peer review process, where experts themselves take part in reviewing the work of another, the majority of the volunteers here, like most editors in Wikipedia, lack expertise in the subject at hand. This is a good thing—it can make technically worded articles more accessible to the average reader. Those looking for expert input should consider contacting editors on the volunteers list, or contacting a relevant WikiProject.

To request a review, see the instructions page. Nominators are limited to one review at a time, and are encouraged to help reduce the backlog by commenting on other reviews. Any editor may comment on a review, and there is no requirement that any comment be acted on.

A list of all current peer reviews, with reviewers' comments included, can be found here. For easier navigation, a list of peer reviews, without the reviews themselves included, can be found here. A chronological peer reviews list can be found here.
