Bowern and her seventy-six contributors (fifty-five of them based in Australian institutions) masterfully deliver on the book's promise advanced in several thoughtfully detailed introductory chapters exploring both the historical landscape and taxonomies of these languages (both old and new) and the intricacies of documentation methods that aim to preserve them [...] Moreover, the Guide goes the extra mile to correct widespread misconceptions stemming from broad over-generalisations about the capabilities and characteristics of Indigenous languages, ensuring that they are presented in an authentic light and given just representation.
