Hello,
Thank you for reaching out for help. First, go to the library website by logging into the AIU Virtual Campus, then clicking on Library in the top navigation bar. I would suggest that you start by using the Search Articles and eBooks search box (shown below), because it will cast the widest net and search most of our library collections This topic is a bit general in subject matter, so we don't have a single database that is definitely the best place to search.
When you search, you should choose keywords that represent the question you are asking and only enter those words. This guide on selecting keywords can help. For this, I suggest doing at least two searches using the following keywords:
- college cost benefit
- college upward mobility
This pulls up articles for me that look useful in this topic area. If you have any other questions or need more help, please let me know!
Here is another tutorial on using the library search.
