I buy books, and I am also Fond of the Public Library for Free checkouts....Love having the option to do either.
I buy books because they may be new releases that I want NOW. And I enjoy supporting the Authors and am willing to pay to support their efforts.
My Greater Phoenix Area Library has a huge selection, as well as the Michigan Library consortium where my Son lives. I nudged him into getting a library card to share with me for an even larger selection. The Michigan Library Consortium has quite a few Epub books which seem to be newer releases.
And, check often on this site and on Sony Connect. Tons of free books available.
