Corpus linguistics is a research method which draws on authentic language examples, collected and organized into 'corpora', or searchable 'bodies' of data. The method was established in the 1960s, and has rapidly developed since then. Now in its second edition, this book provides a step-by-step guide on how to create and analyze linguistic corpora. It has been extensively updated to reflect the most recent developments in this ever-evolving field, and now covers the empirical foundation of corpus-based research, new methodological considerations that guide the creation of a corpus, new kinds of research that can be conducted on corpora, and the most up-to-date information on how qualitative and quantitative analyses of corpora are conducted. Theoretical approaches are introduced in an accessible, easy-to-read way, and the book is illustrated with a wide range of different linguistic corpora, making it essential reading for researchers and students in a number of subfields of linguistics.
