I used my handy dandy google search engine. For the most part google is GREAT at predicting your search and quickly finding the most relevant results. I searched “social networks + education” it gave me a few online news paper articles to read and even a few essays written from other students that where publicized, but nothing that i found useful for actual research.
With the CUNY database i feel the results better fit the assignment which is to do actual research on the topic. Google sometimes sends a lot of random information in your direction. The CUNY database avoids all of that.
But overall, i dont think what search engine you use matters. For the most part i feel you can get just as strong of a research done on either search engine.
