For example, as Ada Maria writes, "early authors seem to have experimented with how to do this, and the resulting works display great variety." " This is reinforced in Glanvill, as he professes that it may be impossible to record all the laws in writing "both because of the ignorance of the scribes and because of the confused multiplicity of these same laws and rules." Furthermore, Maria writes that judges who had the power to administer justice defined customs and decision-making. This leads to the question of whether these literary texts were actually applied in court, primarily because there was always the possibility that they would be interpreted largely according to the judge's own authority. As legal literature serves as a guide, written by people exercising a judicial function, it can be concluded that the literary texts of Glanvill and Beaumanior accurately reflect actual legal practice. Legal literature reflects how the laws and customs of the realm operate within the actual legal framework.
