books that i have read and select out the ones i would least like to keep. sometimes i would be reluctant to give up some book, but at the same time i knew that if i traded it in the reward would be a new reading adventure.
now of course all my books are electronic. i don't even need to keep the electronic books because they are stored in the cloud where my purchase as been recorded. at any time i would like to access that book again, anywhere in the world, using my computer, tablet or phone, i can.
i rarely buy books any more. i make use of the library.
