In the 1930s, Mello e Souza, Cecil Thiré and Nicanor Lemgruber jointly wrote the book "Mathematica Commercial". At the same time, other authors, such as Henrique Desjardins and Luiz Cavalheiro also published books on Commercial Mathematics; and Commercial and Financial Mathematics. These works became known under the aegis of Decree No. 20,158 of 1931, which was part of the Campos Reform and whose objective was the organization of commercial education. In this sense, we question: are there differences between the works of Mello e Souza, Thiré and Lemgruber and the other authors? Are the Campos Reform guidelines for commercial education incorporated into these books? Therefore, the text here delineated aims to construct a historical interpretation, drawing a parallel between the book by Mello and Souza, Thiré and Lemgruber and the other works of the other authors mentioned here, as well as, from these books, to analyze if the orientations of the Campos Reform, of 1931, were or were not incorporated by the authors in their works. As sources we used the decree of Decree No. 20,158 of 1931, and especially the first editions of the books: "Mathematica Commercial" (1932); "Commercial and Financial Calculations" (1936); and "Commercial and Financial Mathematics" (1939). The theoretical-methodological reference was that of Choppin (2004), who makes a state of art about the history of books and didactic editions. The results indicate that the book by Mello e Souza, Thiré and Lemgruber, has some differences in relation to the other works, as for example, they innovated when bringing small texts at the end of the chapters on the mercantile culture, many of historical history. In relation to the Mello legislation, Thiré and Lemgruber, as well as that of Luiz Carvalheiro had a structure similar to that defined by law, except for the book by Henrique Desjardins. As a final consideration, it should be noted that the books of these authors, as well as that of Luiz Cavalheiro, fulfilled the referential function, as put by Choppin (2004), that is, the textbook is a faithful translation of the program established in the legislation.
