Here is some great resources that were given to me by Ron (RGD.)
I have registered for and am using Smashwords.
I have not yet looked into the others.
First up is a web site called
Smashwords that has a short and painless registration that you will want to do. They have a ton of free books with new ones added almost daily in addition to ones to pay for. They have best sellers and original author books as I call them. Now the good thing about Smashwords is that you can download them to your computer and then transfer to Kindle. So if you are so inclined - you could give a copy to someone else, especially the free ones. The site is on the honor system in that they ask if you plan on giving a copy to others (paid for books) that you pay for the extra copy.
Next up is
Ereader News Today. What works best for me is this: sign up on the
EreaderNewsToday Facebook page. Click on the "Like" button. Now each day, sometimes three or four times, they will post in the feed about free books and/or really cheap books. At times you can get $10 to $25 books for under $2 to about 89 cents. They also post links on their website.
Now these books are either linked to Amazon which will download as usual to your Kindle. Or - there are links to the Smashwords site listed above - hence the reason to sign up there. There will be a code on the Ereader site with the link. Use that code to make the books free. Just click and follow, add to cart, insert the code, click update, and then check out. Follow the link, select Mobi and download.
Good for about 20 to 25 free books each week.
ManyBooks. This site has about 29,000 books - and they are all free. Nothing to sign up for. These books are cached actually on Amazon's S3 service. Short version is that sometimes you may request a book that takes a while to download - because it is being encoded - but will be really quick for everyone else. One cool thing on this site is that they have an RSS feed.
And lastly-
Feedbooks.com They have a store, public domain and original books that are free. Honestly I have been there, looked around, bookmarked it but with the above sites and my newsgroup feeds - I will be saving it for when I get the time. Good looking site though.
