I copied this from a website:
The term “white bean” can be correctly applied to any bean that is white or off-white in color. Most of the time, white beans that are sold commercially, either as seeds or as a food product, are marketed under more specific names, such as navy beans, Great Northerns, or cannellini. Though different white bean varieties have slightly different tastes and sizes, their nutritive values tend to be very similar, and they are often interchangeable in recipes.
