Cancioneiro da Biblioteca Nacional

The Cancioneiro da Biblioteca Nacional (Portuguese: [kɐ̃sjuˈnɐjɾu ðɐ βiβliuˈtɛkɐ nɐsjuˈnal], Galician: [kanθjoˈnejɾʊ ðɐ βiβljoˈtɛkɐ naθjoˈnal]; "The National Library Songbook"), commonly called Colocci-Brancuti, is a compilation of Galician-Portuguese lyrics by both troubadours and jograes (non-noble performers and composers) .

The poems were copied in Italy (presumably from a manuscript from Portugal or Spain) around 1525-1526 by the order of humanist Angelo Colocci (1467-1549), who numbered all the songs, made an index (commonly called the Tavola Colocciana [Colocci's table]), and annotated the codex.

In the 19th century the cancioneiro belonged to Count Paolo Brancuti di Cagli, from Ancona, in whose private library it was discovered in 1878.

The count later sold the manuscript to Italian philologist Ernesto Monaci, who left it to his heirs on the condition that it not leave Italy.

A closely related songbook (sister or cousin), kept in the Vatican Library, is called the Cancioneiro da Vaticana.
