The work consists of the conformation of a Chilean history books library generated from the files declassified by the CIA -referring to the historical period from 1968 to 1991- on events of national relevance for Chileans and the world. These documents were declassified by the CIA and other U.S. intelligence agencies.

The work corresponds to an edition and selection that implied the revision of ten thousand of these files, which were reclassified considering that their main material characteristic is the struggle between information and censorship, which contradictorily makes it possible for the file to come to the public light. The work proposes a reading of the documents, based on their visuality and not only on the information.

The intervention was carried out in three branches of Librería Ulises in Santiago: Providencia, Lastarria and Parque Arauco, through different strategies. The 608 books were available to the public and could be purchased by answering a question, which made it possible to put this material into critical circulation.
