Review on OpenScholar by Donald Waller

I like that it is very easy to use, and you can search for information by topic or keyword. It's also free! You don't have to pay any money to access this database of scholarly articles. The only downside is that sometimes there are errors in the articles themselves (like typos). Sometimes they will not link directly to the source article, but rather just provide an abstract which makes finding the actual paper difficult. This has never been a problem with me personally though as I am able to find what I need through other means. If your looking for reliable sources of research papers then open scholar should be at the top of your list. I'm using this service daily to help keep my work load manageable. There isn't anything specific that I dislike about open scholar so far. They do offer many different ways to filter results.
