This volume presents principles and methods of textual criticism aimed at students, outlining palaeographic and codicological features used to evaluate manuscript evidence. It surveys and catalogs Greek uncial and cursive manuscripts, lectionaries, and manuscript service-books, illustrated by plates and organized by chapters that treat particular classes of texts. Separate sections address ancient versions and languages, practical collation techniques, systems of division and dating, and common variants, while appendices discuss facsimiles, indiction, and technical matters. Editorial additions and indexes provide cross-references to scribal hands, past owners, collators, and authorities to support further research.
