Best thing is that Smashwords will have a full listing of books whose authors are sharing them for the week, often at deep discounts. From the site:
Read an Ebook Week kicks off this Sunday. Smashwords is again sponsoring the event for the sixth year running.
Thousands of Smashwords authors will offer free and deep-discounted titles starting Sunday March 2 and running through Saturday March 8.
Readers, starting Sunday March 2 Pacific time, the Smashwords catalog of participating titles will appear at https://www.smashwords.com/books/category/1/newest/1
Readers and Authors: The official Read an Ebook Week hub page is at Smashwords and offers access to banners, buttons and badges you can post on your web site, blog, Facebook and other social media outlets to celebrate your participation in this event. This page will also feature links to promotional or free catalogs to make it easier for readers to find books. Currently I have links to the Smashwords RAEW catalog, and to free books at Apple iBooks, Barnes & Noble and Diesel. I plan to add links to other retailers as well.
Authors: To enroll your book(s) in the promotion, go to https://www.smashwords.com/dashboard/sitewidePromos or click the “Authors, add your books to the promotion” button on the Smashwords home page.
If you’re interested to learn the story behind Read an Ebook Week, read my 2010 interview with Rita Toews at The Huffington Post . Please note that the prior web address mentioned in the interview, http://www.ebookweek.com, is now controlled by a squatter and is not associated with this promotion, so please don’t link to or promote the old address. The Smashwords RAEW page at www.smashwords.com/ebookweek is a better option, and has Rita’s blessing.
The official Read an Ebook Week Facebook page, operated by Ms. Toews, is at https://www.facebook.com/pages/Read-an-E-Book-Week/193882590629749 Show your support for RAEW by “Liking” it on Facebook.
