A big update is coming to David Sparks' iBooks Paperless.
I'm busy preparing the next update to Paperless. It will release some time in the next month. When it comes out, you'll be able to delete the current version from iBooks and download the updated version. You won't have to buy it again. I'll post the update notes and details when it releases. There are new screencasts, new sections, the works.
Paperless takes the mystery (and fear) out of going paperless with your Apple technology. The book includes 32 screencasts, 4 movies, over 26,000 words, and other rich-media assets to turn you into a paperless ninja. The material is accessible to beginners and power users alike with a thorough explanation of all the hardware, software, and workflows necessary to finally conquer paper.
