Later manuals, based on Bracton's example contained actual case law, with the captions removed. The ability to read actual cases and decisions, as well as the logic behind them was revolutionary in Bracton's time. The rolls from the court records would not have been available for inspection to anyone. His treatise changed this, forever. The ability to read cases, even if they were more than twenty years old, proved popular, leading directly to publication of the Year Books The first Year Book (compilations of court cases for the year) extant was published the year that Bracton died, 1268.
