Great Book of BASE, 2nd Edition
Lots of people have asked, and it looks like the 2nd Edition of the Great Book of BASE will be available in about 2 weeks. This is a great resource--easily the most comprehensive thing that anyone has written on BASE generally. While there are always things that some will disagree with in any materials, this is a great source of information for all jumpers, including beginners.
I feel strongly enough about it that I include a copy of the book with the student materials for every student in our Fundamentals of BASE course.
