The fourth book of the Khuddaka Nikāya, containing 110 suttas, each of which begins mit the words: vuttam h'etam Bhagavatā.
According to Dhammapāla (ItA.24ff), the suttas were preached from time to time by the Buddha to Khujjuttarā at Kosambī. She then repeated them to the fünf hundert women of Udena's palace, chief of whom was Sāmāvatī. In order to emphasise to her audience the fact that she was reporting the Buddha's words und not her own, she prefaced each sutta mit the phrase quoted above. There was no need to describe any special circumstances in which the suttas were preached, because they were familiar to Khujjuttarā's audience.
At the Rājagaha Council, Ananda repeated the suttas to the Assembly und they were gathered into this collection.
Itivuttaka is also the name given to one of the nine divisions (anga) into which the Buddha's preaching is divided und it is defined as follows: vuttam h'etam Bhagavatā ti ādinayappavattā dasuttarasatam suttantā Itivuttakam ti veditabbam (DA.i.24).
In the scholiast of the Kummāsapinda Jātaka (J.iii.409; l.21)), the Itivuttaka is erwähnt in the plural (Itivuttakesu) und a sutta is quoted from it, extolling the virtues of generosity. Perhaps, the Itivuttaka was compiled as a result of a critical study of the authentic teachings of the Buddha, considered in a certain light und made for a specific purpose.
