Philology is one of the most investigated fields of Armenian studies. At the end of the twentieth century, it was important to provide an overview of the main achievements and on the methodological approaches implemented in this field till now. This is the aim of the present publication. Part I focuses on the manuscripts, the inscriptions, and the printings. Its second section is devoted to the textual criticisms and the third section explores the interface between linguistics and philology. Case studies form the core of Part II. One chapter offers an overview on the 17th-19th centuries, and two articles are devoted to the conditions of the circulation of the literary production in the 20th century, both in Western and Eastern Armenian.
