Open access databases
While you are at NAU, you will have access to a wide range of academic databases; however, the vast majority of these resources come with large, institutional costs, and are not feasible for individual consumers.
Thankfully, there are a growing number of databases and online resources that are free to the public.
The following list provides a few of the top-tier options. Before that, one note: if you ever need to access a paper for research or personal use, it never hurts to email the author/s and ask for a draft copy.
