For the post-war careers of Hannibal and Scipio, the primary sources are Livy, Appian, Cornelius Nepos's life of Hannibal, and Plutarch's Life of Flamininus for the circumstances of Hannibal's death. The final years of both men are sparsely documented relative to their wartime careers, partly because the ancient historians were most interested in the great battles and partly because both men spent their last years in relative obscurity. The inscription attributed to Scipio's tomb, ingrata patria, ne ossa quidem habebis, is recorded by Livy and has been widely treated as authentic, though it may be a later invention consistent with the tradition of Scipio's bitterness.

For the social and economic transformation of Italy, the fundamental ancient sources are Appian's Civil Wars for its account of the agrarian problem, and Plutarch's Life of Tiberius Gracchus, which presents the land crisis and its history explicitly. The modern historiography is extensive and contested. P.A. Brunt's Social Conflicts in the Roman Republic, published in 1971, remains influential. Keith Hopkins's Conquerors and Slaves from 1978 provides the most rigorous analysis of the slave economy and its relationship to the military transformation. Nathan Rosenstein's Rome at War: Farms, Families, and Death in the Middle Republic, published in 2004, challenges the traditional narrative about smallholder displacement and should be read alongside the older scholarship.

The cultural encounter with Greece is handled most fully in Erich Gruen's Studies in Greek Culture and Roman Policy, and more accessibly in Mary Beard's SPQR, which places the Scipio-Cato tension in the broader context of what Rome was becoming in the second century BCE. Elizabeth Rawson's Intellectual Life in the Late Roman Republic is also useful for the longer-term literary and philosophical consequences.
