In an effort to get out the word about how wonderful eBooks are, some folks got together and decided to throw this, sort of, holiday. Some publishers and such are offering free eBooks and you all should really pop on over to Dear Author for their string of Sunday posts on all things eBooks. Here's the website for eBook Week- http://www.ebookweek.com/
Here's the link to Dear Author- http://dearauthor.com/wordpress/2009/03/08/how-to-decide-between-the-sony-and-the-kindle-eink-readers/ -click on the tag 'ebooks' at the top of the post to read all the other posts on ebooks.
And here's a link to Cerridwen Press's free eBook for this lovely celebration- http://www.jasminejade.com/p-4329-gryphons-quest.aspx -It's YA Fantasy.
If you don't have an eBook reader, eBooks can be read on your computer too.
