The Archives Department gathers documentary collections of private origin linked to important personalities and institutions of the country's culture, politics and intellectual life from the beginning of the 20th century to the present day. These archives usually contain letters, manuscripts, pamphlets, leaflets, flyers, press clippings and other printed matter, periodicals and photographs. The unique and original character of archival documents makes them important sources for research and for the creation of all kinds of audiovisual, educational and cultural productions. At the end of 2016, the Archives Department received the Historical Institutional Archive, which houses the documentation produced by the National Library in the development of its missions and functions from the 19th century to the present day. Some of the valuable documents that can be found are correspondences, cash books, books of purchases and donations of works, drafts of notes, records of expenses, among many others. Since 2017 the collection is in the process of organisation (classification and arrangement), description and opening to public consultation.

The Mariano Moreno National Library of the Argentine Republic, founded as the Public Library of Buenos Aires in the context of the May Revolution, cherishes and protects, through state-of-the-art library technology, the materials that forged the country's different ideas and eras, which it makes available to citizens as an opportunity to rethink the enigmas of its collective culture.

The National Library, created by Mariano Moreno on September 13, 1810, treasures and safeguards, through the most modern library techniques, the materials with which the different ideas and eras of the country have been forged. In its collections, made up of numerous documents, manuscripts, books, magazines, newspapers, photographs, maps, engravings, audiovisuals and scores, a living culture persists, waiting to be rediscovered by the gaze of its readers and researchers, recognising the tones of a heterogeneous country and the points of view of a past that never ceases to produce questions and project images onto the present.
