The Language Centre was founded in 1970 as a language research department in the University of Ghana, under the then Faculty of Arts. Its mandate was to focus on research and teaching related to the improvement of performance in English, the official language, and the various Ghanaian languages as vectors of education, culture and community interaction. Since the 1970s, the Centre has been focusing on research related to language learning, teaching and assessment, language endangerment and documentation, multilingualism, intercultural communication, and the interconnected areas of language and literature. This book, in essence, reflects these research areas, but more than that the constitutive research articles were produced jointly or severally by different generations of directors and research fellows of the Centre, over the four decades of the organization's existence. The ten chapters of this commemorative anthology comprise selected research articles from a very large pool of previously published works with continuing relevance, as well as more recent works that have not yet been published. The book is not designed for release as a discrete and independent publication. On the contrary, it feeds into a much wider set of commemorative collections from diverse units, all of which are thematically linked in a manner designed to project the mission of the University of Ghana.
