Articles in peer-reviewed/refereed journals are critically reviewed and evaluated by peer experts or scholars.
These "peer reviewers" are experts in the field and assess the quality of the methodology, data, analysis, findings, conclusions, and claims presented in the article and determine that the work is worthy of publication.
The library collects peer-reviewed/refereed journals to assist you in your research.
Information indicating if a journal is peer reviewed/refereed is often indicated within the publication.
One example can be found on SAGE's Journal of Early Childhood Literacy website
