Is there an easy way to import Kindle books?

Mark, I can’t do it either. I actually have an ORIGINAL Kindle Fire (yeah, it’s an antique!) and Amazon won’t allow a download of the text to my computer. It will stick it in the Kindle app on my computer, but not allow me to have a text file to manipulate - which really chaps my hide since I paid for the book! I am wondering if buying from Barnes and Noble online might make it easier…
