Szmańko, Taras (Wydawnictwo Naukowe Uniwersytetu Papieskiego Jana Pawła II, 2010)
The Author describes the methodology of research of Cyrillic texts, both manuscripts and old prints. He takes into consideration such issues as compiling the most compete possible set of sources, being aware of periodization of changes in the liturgical texts, problems connected with dating and localization of books, questions of the original manuscript and of the use of technical means in the research of sources. Relying on a long experience of work with manuscripts and old printed books collections, the author presented a series of suggestions for effective source research work. Special attention is paid to identification of liturgical texts according to the content criterion.
