The series will include approximately 60 volumes (each comprised of approx. 400–600 pages and 15–30 chapters). Each volume will focus on the most central aspects of its topic in a clear and structured manner. As a series, the volumes will cover the entire field of present-day Romance Linguistics, but they can also be used individually. Given that the work on individual MRL volumes will be nowhere near as time-consuming as that on a major reference work in the style of LRL, it will be much easier to take into account even the most recent trends and developments in linguistic research.
