New Guidebooks for Navigators & Adventurers

I saw an email on the new guide books for Adventurers and Navigators. The question is, where do we get them? Or, are they part of the new handbook? Can anyone confirm? Thanks!

The new books can be purchased in the Trail Life Store. I have attached a link below =)

There are some updated guides there for patrol planning and such and more are still coming which will be available in the same location I would assume.
