Crucial Readings in Functional Grammar is an invaluable resource to anyone working in Functional Grammar, student and scholar alike. It contains important articles that have led to new avenues of research in the theory beyond Dik's two-volume Functional Grammar (1997), each concluded with a short paragraph with suggestions for further research. The book also contains an introduction to current Functional Grammar theory by the editors. Crucial Readings is unique in bringing together in one volume the various ideas that complement Dik's canonical presentation of the theory. The editorial contributions provide a comprehensive review of Functional Grammar publications.
