March 7th to 13th is the second annual "Read an e-Book Week". Many publishers and authors (including yours truly) have made books available for free or at a discount during this week.
Visit the "Read an e-Book Week" web site to get great information on electronic reading, including a list of the authors participating.
While I can't imagine paper books will be gone any time soon, electronic reading is becoming steadily more popular, and this week is a great time to give it a try if you haven't already.
If you're a fan of commercial women's fiction, both of my ebooks are available for free this week through my author page at SmashWords.com. If not, there are tons of other books available.
Or there would be, if electronic books weighed anything. :)
