Reasons for consideration:
The Diario de Pernambuco is acknowledged as the oldest newspaper in circulation in Latin America (see : Larousse cultural ; p. 263) ; the timeframe proposed would offer insights into early Brazilian commerce, social affairs, politics, family life, slavery, and such ; published in the port of Recife, the Diario contains numerous announcements of maritime movements, crop production, legal affairs, and cultural matters.
The 19th century includes reporting on the rise of Brazilian nationalism as the Empire gave way to the earliest expressions of the Brazilian republic. The 1910s and 1920s are years of economic and artistic change, with surging exports of sugar and coffee pushing revenues and allowing for rapid expansions of infrastructure, popular expression, and national politics.
