FWIW, I use two books for myself and helping others and my guess if that they would cover at least 75% of what is asked here for questions. They are Don Kelly's National Bank Note book and Ira Friedbergs Paper Money of The United States.
They are a bit pricey, but are pretty much a one time buy that will help with a lot. Of course, asking here is free.
