This is a brief list of databases that are likely to be helpful for your assignments. CU's libraries subscribe to almost 1500 databases, so if you're not seeing something that would be a good fit for your assignment, contact a librarian. We'll be able to point you to one that has the information you need!
Most, but not all, of the resources in these databases are from peer-reviewed academic journals and you'll find a mix of primary and secondary sources. If you have questions about whether or not an item is suitable for your assignment, librarians are happy to help with that.
