First, use Google Scholar and search for the title of the article. Look for the link to the pdf or UC eLinks on the right side. If you do not see the article, use the Citation Linker where you should see if the UCSB Library has access to it or use the Request function to request a copy through Interlibrary Loan.
Scholarly journals (also called academic journals) contain articles written by, and addressed to, experts in a discipline. Scholarly journals present the research of experts in a field, although these journals also often carry opinion pieces or even advertisements unique to the field addressed by the journal. Publication cycles vary for scholarly journals, ranging from yearly to monthly but most frequently they are published bimonthly (every other month) or quarterly.
Peer-reviewed journals (also called refereed or juried journals) send submitted articles to one or more experts for review before deciding to publish them. This review process helps ensure that published articles reflect solid scholarship in a field. Most often, the experts reviewing an article make critical comments on the text, comments that the author must incorporate into the article before its publication.
While not all scholarly journals are peer-reviewed, it is usually safe to assume that a peer-reviewed journal is also scholarly.
Many of the journals indexed in specialized databases are scholarly but those databases do not tell you whether a journal is peer reviewed or not.
To find out if a journal is peer reviewed look at the submission process on their website for authors.
You can also ask a reference librarian.
These are a great way to get an overview of your topic. Try searching through Annual Reviews, then try your search in any database and use the word "review" as part of your search. UC Library Search and Academic Search Complete have a number of review articles in them. Note that some reviews are actually book reviews.
