Variation in English World-Wide

"This book provides a comprehensive overview of variation in English across the globe, by analyzing a large corpus of texts from the English speaking world. The analysis draws on a larger number of individual texts and linguistic features than previous studies have done.

The results provide a testing ground for theoretical models, and highlight the importance of register in mediating linguistic differences across national varieties"--
