Databases will search of many journals to help you find articles related to your topics. Some databases will provide the full article while some will just provide you with a summary which the full articles can be requested through Interlibrary Loan.
What is Peer Review?
Peer-reviewed, refereed, or scholarly journals have articles that have been reviewed by experts in the field. Not all articles in peer-reviewed journals are reviewed, however. Some may be news, opinion, or short reports. Many databases are either all peer-reviewed journals or have a check box to limit a search to just peer-reviewed journals.
