L'homme armé
Many of the series are devoted to works of a single composer, and in some cases they are organized into sub-volumes because of their size (for example, "Volume 1" contains the works of Guillaume Dufay; it actually consists of 6 separate bound volumes, separately containing motets, masses, mass fragments, other liturgical music, and secular songs). Other series contain anthologies and contents of codices and manuscripts, documents which typically compile the work of many composers: for example, series 46 has the complete Old Hall Manuscript of music from early 15th-century England, and series 85 has the six anonymous L'homme armé masses from Naples.
