Berthe van Regemorter learned the craft of bookbinding in Brussels before joining the workshop of the famous British bookbinders Sangorsky and Sutcliffe. In 1923 she entered the Vrije Akademie in Antwerp as an instructor. A turning point in her carreer was Henry van de Velde's request to become a lecturer in his newly founded school of visual and decorative arts, La Cambre. But perhaps more important still is the fundamental role that Van Regemorter played in the development of the field 'bookbinding-archeology'. Thanks to her, the current popularity of this research results in the annual publication of several essays and articles. She also led the way in establishing a methodological structural analysis of bookbindings. This volume presents all the work of Berthe van Regemorter, commented and translated into English by Jane Greenfield. The follwing topics are treated: the structure of the binding from the origins of the codex, through Coptic, Armenian, Byzantine, Oriental and European bindings until the late Middle Ages.
