During soft-opening previews for Disney's Animal Kingdom, in addition to a guide to the new land, Disney also provided guests with these "Field Guides," which included information on Na'vi language along with descriptions of some plants and animals you can see and hear while visited Pandora. If you want to know the names of the local flora and fauna or play along with the Cast Members who are still committed to the idea that guests have left a theme park and are visiting a foreign world, then this guide is still useful today.
I acquired my copy of this Field Guide during a May 19, 2017 visit.
