In the context of the BDMG Cultural Institute’s 30th anniversary, this book compiles studies about a diversity of subjects into two sections: the first revolving around the city of Belo Horizonte, printed on gray paper stock; and the second around the state of Minas Gerais, printed on yellowish paper. While each article is introduced by a different kind of ruled paper, content originally written as footnotes was instead treated as sidenotes, making a subtle allusion to marginalia. A plastic dust jacket commonly used on notebooks underlines the book’s nature and protects the object produced to be freely distributed.
