If it is out of copyright, you can probably find it here. In 2019 a twenty-year extension to copyrights ends, which means that those books will become a huge addition to this already massive collection of FREE TO DOWNLOAD BOOKS in text, epub, mobi, PDF, and other forms, as well as AUDIO versions, through LIBRIVOX. This is not a library. You download it, you own it. I have downloaded books and short stories from Gutenberg.org for many years now.
Gutenberg appreciates donations, but they are not in the least bit pushy about it, which makes me want to donate.

Overdrive connects to any libraries. You can connect to your library to get loans of ebooks, audio books, and even movies. You can download the ebooks and audio books or read online, or listen online, or both, if you wish. The selection is best if you get a card at a larger city library. Library cards are often available online or by using your phone number. Get OverDrive and find more to read than you have time left in your life to read. Best of all? IT'S FREE! Also: No adds and no weirdness or risks.

After years with scribd, I cancelled and will never return. Years ago, Scribd had a wonderful book plan. The rules changed dramatically over the last year (2016). What I signed up for is NOT what Scribd delivers. It went from unlimited and the ability to read books offline to only three books each month, only available to read on the internet. No internet means no book access.
I get a much better deal at my county library for FREE. The selection is also broader at the library. The public library loans e-books and audio books and I may borrow up to ten or more (enki and larger city libraries allow far more book downloads) at a time. And I can read them OFFLINE. Scribd cannot match this service even though they charge about ten dollars each month. Don't bother with Scribd.
