If an item in eScholarship has been marked as having undergone peer review (either by the original depositor or via the metadata received from a third party), the term "Peer reviewed" will appear within the Author & Article Info tab just above the item's inline preview.
Why aren't items without peer review information marked as "Not peer reviewed"?
Most peer review metadata we receive only includes either an affirmative "peer reviewed" statement or no peer review information at all. Since we can't be sure items without peer review statements were not peer reviewed, we cannot confidently label the item as "Not peer reviewed."
