The different methods used to produce each edition are detailed in this field. They include engraving, lithography and, in the case of printed material, movable type. For example, in the volume of Posthumous Works brought out in 1855 by A. M. Schlesinger – various extracts from which appear in OCVE – the series title page and preface were printed, the decorative plate lithographed, and the music text engraved.
