Book excerpt: The book presents authentic texts in two Yukaghir languages, Tundra and Kolyma Yukaghir, an isolate group of languages spoken by few small communities in Siberia. The major goal of the book is to make primary Yukaghir data accessible for readers who have no previous knowledge of these languages. Each text is provided with a detailed morph-to-morph translation following thecurrent linguistic standards, as well as with idiomatic English translation. In addition, the book contains Yukaghir-English vocabularies for both Yukaghir languages, with cross-references to all text occurrences of each word, a set of comprehensive morphemic and grammatical indices to text corpora, and abrief overview of basic ethnographic and grammatical facts. The principles of text representation are described in a user's guide. The book will serve as a useful source of data for scholars of the Yukaghir languages and cultures, as well as for anyone interested in cross-linguistic or cross-cultural studies.
