Access to academic databases

I'm sorry but I really don't think you can find a free academic databases with a good quality of researches and articles. knowledge is power and for power you must pay. 

In Georgia, our statewide academic library consortium has subscribed to a collection of databases in a project named GALILEO. Public libraries have been able to subscribe to a subset of these databases working through the same project, so some of these databases are available in our local public libraries. The number of databases available is smaller, in part because some of the databases are not relevant to the public library community. Some of the academic databases are included, however.

jeffheck's absolutely right. I'm a librarian in Indiana, and our state library cooperative also administers such a program (called INSPIRE). Here's a list of other state library projects from their website (Galileo is on the list):
