Bonifacio del Carril has attempted to clarify some aspects of the Argentine Declaration of Independence. In the first and most interesting section of his book, “Cómo se redactó la declaración,” the author uses close textual analysis to compare the Argentine document to the United States’ Declaration of Independence. The deputies at Tucumán clearly modeled their declaration on the American precedent but adapted it to conform to the juridical and colonial traditions of Argentine history. In the second section, “Cómo se proclamó la independencia,” Carril discusses the various editions of the document. Handsome reproductions of the Declaration and extensive explanatory and bibliographic footnotes add to the value of this book.
