"In these pages, the reader will be able to take a tour of the memory of that exhibition, in which academics of the IIB, organized into three chronological areas, corresponding to the 16th to the 19th century, and the 20th and 21st centuries, carried out a curatorial work to show the evolution of the book in Mexico and its various configurations over more than five centuries. The collaborative work collects some of the treasures of the bibliographic heritage protected in this Library with the aim of showing the public its history and its value within the written tradition of our country. Among these jewels are some manuscripts of the ancient indigenous cultures, the European incunabula, which arrived with the New Spanish trade, the first prints of America and the volumes that were appearing with the progressive and increasingly fruitful development of the publishing industry in Mexico., to the 21st century and registering the change from paper to electronic and digital media. The ink tradition of the National Library of Mexico is protected in its rooms and collections, on the shelves of its collections, ancient and contemporary, even also in its safes and in the beautiful Sala Mexicana. Therefore, this is an invitation to know part of that wealth, a written memory that, we must not forget, is, in addition, a common good of all Mexicans." (HKB Translation) --Flaps.
