To get an idea of the mainstream and where the general mood is, I'd start from Wikipedia.
For bank money:
- https://en.wikipedia.org/wiki/Endogenous_money
- https://en.wikipedia.org/wiki/Monetary_circuit_theory
For central bank money (basically cash):
- https://en.wikipedia.org/wiki/Money_creation
- https://en.wikipedia.org/wiki/Chartalism
Note that both monetary circuit theory and chartalism are considered _heterodox_ economics. Yes, "regular" economics is called _orthodox_!
I personally think Modern Monetary Theory nails it. The MMT Podcast (http://themmtpodcast.com/) is accessible, entertaining, and non-dogmatic. A beautiful introductory book is "1000 Castaways: Fundamentals of Economics" by Clint Ballinger.
