This essay attempts to fill some of the gaps in our knowledge of Corral's public life, especially for the period of his vice-presidency. It is divided into three parts, covering Corral's career in state and national politics and in exile.

The secondary sources for the Porfiriato are inadequate to a study of Corral's career. Therefore, research centered mostly on primary sources, chiefly those in the Colección General Porfirio Díaz (Cholula, Puebla), Mexico City Newspapers, the Corral Papers in the Centro de Estudios Históricos (Mexcio City), and the Archivo General del Estado and Archivo Histórico in Hermosillo, Sonora.
