Good source of books from this thread.
From Amazon:
- Customers Who Bought This Item Also Bought
This is hit or miss, because sometimes the customers buy all the books from the same author, so I don't get to have a variety or know what are other books out there
- Recommendations
Both Amazon and Kobo have good personalized recommendations. Kobo also has good list of recommendations when you add a book to the cart
- List such as Books > History > Americas > United States >
21st Century
Some books have this list at the bottom, some don't. To find other similar books, I would click these links
