While the Raccolta contains hundreds of wonderful prayers that we would all do very well to continue saying, it is not legally in force anymore. The old indulgences were abrogated when the revised Handbook of Indulgences was promulgated by Paul VI and later by John Paul II, so look at those.
In my morning offering each day I pray “I have the intention to gain all the indulgences attached to the prayers I shall say this day, and to the good works I shall perform this day…” for myself and for the souls in purgatory.
