Book excerpt: Using the Web as Corpus is one of the recent challenges for corpus linguistics. This volume presents a current state-of-the-arts discussion of the topic. The articles address practical problems such as suitable linguistic search tools for accessing the www, the question of register variation, or they probe into methods for culling data from the web. The book also offers a wide range of case studies, covering morphology, syntax, lexis, as well as synchronic and diachronic variation in English. These case studies make use of the two approaches to the www in corpus linguistics - web-as-corpus and web-for-corpus-building. The case studies demonstrate that web data can provide useful additional evidence for a broad range of research questions.
