From Laura Gibbs’s Bestiaria Latina: Gaudium Mundo website:
Welcome to the 2012 edition of Latin Holiday Songs for the month of December. This started as a project back in 2006, and thanks to people's contributions, the list has now grown to 80 Latin songs. Below you can see the complete carol collection, and you can even add a Latin Holiday Song widget to your own blog or website!
