In terms of references, tons and tons and tons of prior art defining money and so forth. A book I recently enjoyed a great deal is:
The Nature Of Money, Geoffrey Ingham
https://www.amazon.com/Nature-Money-Geoffrey-Ingham/dp/07456...
And this more recent Bank of England paper is exceptional:
https://www.bankofengland.co.uk/quarterly-bulletin/2014/q1/m...
The starting point I would recommend is bottom up, through accounting and financial statements. Core knowledge, of both practical and intellectual value. Tons of books here, I particularly like
Thomas Ittelson - Financial Statements
Accessible, straightforward, friendly.
After that, any of the collections of
Warren Buffett's Letters to Shareholders
are both entertaining and intellectually valuable, and provide great insight. Read forward, eg, from his first letters in the 1960s, to now.
One of the realizations in the journey is that there are, and have been, a lot of different kinds of money- credit money and exchange money and asset money and so forth. A relatively abstract/intellectual but immensely useful survey is
The Nature of Money - Geoffrey Ingham
The concept of an asset is critical to the functioning of the financial system. New kinds of assets are created all the time. One of the best written books I have read recently goes into venture capital and debt asset creation:
The Code Of Capital - Katharina Pistor
The role of different kinds of money in history, especially US history, is absolutely fascinating. I am in the middle of
American Bonds - Sarah Quinn
and can recommend.
I do not especially recommend the Dalio books or Graeber's Debt or Ferguson's books. They are fine but I did not find them helping me build understanding. Not quite junk food, but definitely not protein.
I unfortunately have not found any of the books I have seen about the Federal Reserve to be worthy of recommending. My wife works there and so I have perhaps a unique perspective. But nothing conveys the challenge and the mechanics of what they do. Still looking. The papers the various Fed banks publish, as well as the papers published by the Bank of England, are uniformly outstanding.
Finally, some of the bitcoin people have written about money. Tho I am a believer in bitcoin I absolutely recommend against most of them, especially Saifedean Ammous's book. Do not read.
Good luck!
