Printed books will never disappear completely, but it's hard to find more convenience than a digital book. You can download as many as you want and cart them around on a single thin, light gadget.
And just like physical books have libraries, so do eBooks. Open Library is the largest, with millions of books available for free download.
What's more, Open Library is attempting the seemingly impossible feat of cataloging every single book ever written. Each book's page has information on the book, the author and relevant links.
Find a mistake on the entry for your favorite book? You can edit mistakes and add information. You just need to set up an account using your name and email address.
How to get the eBooks
Open Library works on almost every gadget. The eBooks are in PDF and ePub formats. You can read them on a computer, in a Web browser, on mobile gadgets and eReaders. Kindle users can convert ePub files for Kindles using a program like Calibre.
Keep in mind that most eBooks can only be lent for 14 days. After that, the borrowed books disappear from your eReader. This keeps you from racking up late fees like a conventional library book, but it means you can't take a month to read the book.
Publish your own eBooks and make money
People ask me all the time how they can make money, and there are plenty of ways to do it. However, writing a book is one that many people overlook. I believe everyone has a book in them. Fortunately, no one said it had to be a novel. Whatever your subject, no matter how big or small, there's most likely an audience somewhere. The trick is getting your work in front of them.
