Many people would like to know how to offer free e-books to increase the traffic of visitors in their blog. Two main questions being considered are the following:
1. Where do I get the free e-book I could give away?
2. How do I install the code needed to automatically give the e-book for download to those who will subscribe?
I will cover the first question here, being the easier one. (Watch out for later articles on the second).
Where do I get the e-book for giveaway?
1. You write your own ebook
2. You ask someone to write an e-book for you.
3. You get the e-book free from the internet!
I think that for a beginner, the easiest way would be number 3 
For now, let me give you some tips where you can get those e-books for free
1. PROJECT GUTENBERG http://gutenberg.org
There are many classic books in this website which are already in the public domain, meaning they are not copyrighted anymore and you could offer them free.
2. PLR BOOKS
PLR Books are private label rights books that have more recent and relevant topics. They can be downloaded in several sites ,with the help of a google search of course. Just type in PLR and hit that search button!
Here’s an example I have already searched for you:

3. I have also listed other sources of free e-books which you can read here (Thousands of Free E-book References).
Great article and really useful information!
