There are some distinct advantages to using the electronic PDF versions of TaoA:M and the Technical Reference.
One benefit is in searching for specific topics of interest.
You can't do this with paper-based books.
When you are working through the TaoA:M exercises you may find turning on Bookmark view to be useful too.
This will let you access all the exercises easily from the same menu.
Both TaoA:M and the Tech Ref can be downloaded via Hash Inc's Reference Materials page.
