Scholarship and Criticism:
While criticism is scholarly and generally published in academic journals for an academic audience, reviews can be written by anyone and are generally aimed at the general public. They are generally published at the same time the work reviewed is released and can capture contemporary, popular opinions.
To find reviews, include "reviews" as a subject term in your search or choose "reviews" under content type when searching the catalog.
