Dictionaries and encyclopedias of liturgy and worship (selected European, in progress)
Dictionnaire encyclopédique de la liturgie. Ed. Sartore, Triacca, & Delhougne. 2 vols. Brepols, 2002.
A revision of the Nuovo dizionario di liturgia of 1984. Comparable to the DACL in ambition, but focuses on the post-Vatican-II liturgy of the Catholic Church. Refers to older forms in the course of treating that. Vol. 2 concludes with a "Lexique liturgique".
