Hi. For one of my classes, I am supposed to be writing an essay arguing for the existance of the Bermuda Triangle and why it should be included
I think your main term would be Bermuda Triangle. In some seaching if you are getting a lot of other stuff, try placing "" around "Bermuda Triangle". Other terms you might try with Bermuda Triangle are disappearances, mystery, theory or theories.
I did a little looking around the databases for journal articles. In Sage Premier, I found this article: http://sac.sagepub.com/content/3/6/48.full.pdf+html Other databases to try are GreenFILE and Academic Search Complete. All of these databases are found on our subscription database page.
If you need more assistance, please contact me directly. Good luck with your essay!
