Abstract
This article explores several issues pertaining to the role of titles in Byzantine literature. Firstly, some methodological questions are raised regarding their authority and authorship as well as the delineation of the research subject. Secondly, a specific case is discussed of how a 9th/10th-century anthology uses titles to identify the writings it quotes from. In a more extensive third and final section, the semantic evolution is retraced of the term ὑπόμνημα, which has been used with quite diverging meanings throughout Greek literature
