While hard copy books will still be great permanent reference sources, the plethora of fast-moving printed journals seem ripe for electronic disruption. I wouldn't be surprised to find that most journals as we know them eventually go the way of the dinosaur. As proof comes this from the ACC:
The Journal of the American College of Cardiology (JACC) will be available on the Amazon Kindle e-book reading device starting this March. JACC is the first cardiovascular journal on the Kindle platform and the second medical journal after the New England Journal of Medicine. Visit the Kindle store on amazon.com beginning on March 12 to order and learn more. Also, bring Kindle to ACC.10 in Atlanta to download the meeting abstracts and final program.Welcome to the 21st Century!
