The full title of this work is Raccolta delle orazioni e pie opere per le quali sono state concedute dai Sommi Pontefici le sante indulgenze (Collection of Prayers and Good Works for Which the Popes Have Granted Holy Indulgences).
The book was first published in 1807 by Telesforo Galli, in association with the Sacred Congregation of Indulgences and Holy Relics, with successive editions in 1810, 1812, 1814, 1818, 1825, 1831, 1834, 1837, 1841, 1844 and 1849. Following official approval by a Decree of 15 December 1854, later editions were issued directly as publications of the Holy See by the Sacred Congregation of Indulgences and Holy Relics (which in the  reform of the Roman Curia by Pope Pius X was united with the Sacred Congregation of Rites). A general revision was carried out in 1877, declaring that the revision alone was from then on authoritative. Later editions of this were produced in 1886 and 1898.
Approval of the Roman Congregation was required for publishing a complete translation of the work.
By his bull Indulgentiarum Doctrina of 1 January 1967, Pope Paul VI ordered a revision of the collection of indulgenced prayers and works "with a view to attaching indulgences only to the most important prayers and works of piety, charity and penance". Since then the official collection of the currently indulgenced prayers and good works is called the Enchiridion Indulgentiarum.
