Book excerpt: Working with Specialized Language: a practical guide to using corpora introduces the principles of using corpora when studying specialized language. The resources and techniques used to investigate general language cannot be easily adopted for specialized investigations. This book is designed for users of language for special purposes (LSP). Providing guidelines and practical advice, it enables LSP users to design, build and exploit corpus resources that meet their specialized language needs. Highly practical and accessible, the book includes exercises, a glossary and an appendix describing relevant resources and corpus-analysis software. Working with Specialized Language is ideal for translators, technical writers and subject specialists who are interested in exploring the potential of a corpus-based approach to teaching and learning LSP.
