Ask HN: Where to find peer-reviewed articles
What I've found so far is:
scholar.google.com http://www.doaj.org/ http://magportal.com/
Can you recommend any others, and ideally, tell us what they are good for?

Two of the biggest providers that I've used frequently in the past are EBSCO Host and ProQuest. Both have subscriptions to large and sometimes overlapping journals. I found EBSCO Host a little easier to use if I wanted to browse an entire journal over the span of time. ProQuest had more flexible and reliable search results. Both will allow you to find tons of peer reviewed papers.
Also, if you want to explore who has cited who, and who wrote which papers, look to ISI Web of Knowledge. It has a cool citations explorer that lets you visualize citations and authors.
Finally, contact some experts in your field. If looking at peer-reviewed content, get a hold of a university professor in the field of interest, because they will be able to tell you which journals are A or B journals, and which ones to avoid. You'll likely want to target primarily A journals, and sometimes B journals, but filter out the rest.
