For those who do not already know of it, this is Google scholar. It searches only scientific/academic journals, patents, law, and books.
It is not infallible, so called predatory journals can find their way into the results, but it is far more stringent than a general Google search and is used often by academics and scientists engaged in secondary research.
I would also recommend pubmed.com (there are many open source articles available), and [snopes.com] for fact checking.
Thank you... I added it to my home sceen and I will use it.
