Hispanic Studies Companion to Medieval Iberia is a large-scale work with complex objectives, not only because of the academic demands involved but also because the structure of the work makes it difficult. The work is part of a larger book series, which is made up of three other volumes and deals with Hispanic history, from the Middle Ages (the volume reviewed here), through the Enlightenment, Modern History (which includes the Colonial period of Latin America and the Caribbean) until reaching the Spanish 19th century.
