This guide compliments the three digitized microfilm monastery manuscript collections from St. Catherine's Monastery, the monasteries on Mt. Athos, and the Greek and Armenian Patriarchates in Jerusalem. The materials listed here comprise maps, photographs, sound recordings, moving images, manuscripts, rare books, and other items which pertain in varying degrees to these three manuscript collections. They add supplementary and contextual information to these manuscripts. An index of authors and genres, some research tips, and a glossary of genres and works for these manuscripts have also been added to aid the researcher.
