The NVC “textbook”–Nonviolent Communication–A Language of Life, by Marshall B. Rosenberg, PhD; 3rd edition, Puddledancer Press.
I use this as the NVC “textbook”. Many other books and materials by Marshall and by a host of trainers are also available from The Center for Nonviolent Communication (see below), or elsewhere..
