Liturgical books of the Roman Rite

The liturgical books of the Roman Rite are officially issued books that contain the words of the prayers to be recited and indicate the actions to be performed in the celebration of the Catholic liturgy as done in Rome. To the titles of some of these books, the adjective "Roman" is attached, so as to distinguish them from the liturgical books intended for use in other liturgical rites. An example is the "Roman Missal".

These liturgical books have been classified as seven: the Missal, the Pontifical, the Liturgy of the Hours (in earlier editions called the Breviary), the Ritual, the Martyrology, the Gradual, and the Antiphonary. Another sevenfold list indicates, instead of the last two, the Cæremoniale Episcoporum, and the Memoriale Rituum.

In reality, the number is not fixed. Some names, such as the Ritual and the Pontifical, refer not to a single volume but to a collection of books that fit within the same category. Official liturgical books that appear in neither of the above lists also exist, such as the Lectionary and the Evangeliary or Gospel Book. The 28 March 2001 Fifth Instruction for the Right Implementation of the Constitution on the Liturgy of the Second Vatican Council listed several more. Liturgical books exist also for rare occasions, such as the Order of Rites for the Conclave and the Order of the Rites for the Beginning of the Petrine Ministry of the Bishop of Rome, issued in 2005.

Other liturgical books that no longer exist today, were in use in the past, such as the Epistolary and the Sacramentary (in the proper sense of this word). The catalogue of the illuminated manuscripts of the British Library indicates how varied were the classes of liturgical books for the celebration of Mass and the Liturgy of the Hours.
