A still underexplored research area within corpus-based translation studies, learner translation has been gaining remarkable interest and momentum during the last two decades. Learner translation corpora - Exploring regularities and variation in student translation represents the first book-length exploration of the affordances of these novel corpus resources. The book provides a state-of-the-art account of this burgeoning research field, offering a detailed and comprehensive description of its theoretical and methodological background, and demonstrates through empirical case studies based on the English-Italian language combination how learner translation corpora can contribute to better descriptions of student translation as well as to theoretical, methodological and descriptive advances in corpus-based translation studies.
