Not counting the books I read, I currently have 747 ebooks on my Kindle. Actually much more than that because of ebooks collected into one like H.G. Wells, Jules Verne, Edgar Rice Burroughs, Robert E. Howard, etc, etc, etc...
My goal however is to get that 747 number up to just over 1,000. Let’s say 1,012. :)
Then the next project is to better sort them into folders. :/
I read tons of free books on my kindle. I even pay for one occasionally. Except for the self-published ones, almost all the free ones are very old, and usually quite good, but I’ve many happy hours reading them.
