The book North American Currency by Grover C. Criswell Jr. (1969) is a thousand pages long and covers a wide array of currency, including notes from Mexico and Canada. It lists a plethora of notes from banks as well as merchant's scrip. Although not exhaustive, it is a good resource on notes as it has notes from various states listed. Criswell's catalog numbers for these notes are still in use today. So although the book was published over 40 years ago, it is still a useful reference.
The book also presents a price guide for the notes by providing two values for each note, one for circulated and another one for uncirculated examples. While the prices are out of date, one can see what these notes were worth back in the day and compare their values to today's market. Keep in mind that the US dollar is worth much less today than it was back then. Rarity values however, are not listed.
