Talking about the archives is talking about history, they are the testimony, evidence and record of the daily events of an institution.The historical archive is the heritage that reflects and safeguards the documentary memory, a direct source of legitimacy and identity to know and disseminate the past.

The Historical Archive of the Chamber of Deputies, located on the basement of building D, has an approximate of 1,436 linear meters of files, among the collections are:

The "Old Book Collection", which consists of 75 copies from 1821 to 1920, in which Book I, contains the Act of Independence.
The collection of credentials of the Deputies, which starts from the XXVI to the LXIV Legislature.

The needs for better preservation and dissemination conditions led to the implementation of the Project to relocate the Historical Archive in the Old Guard of San Lázaro. This historical place has marked the Mexico City limit and connections with towns located to the east since pre-hispanic times, serving later in the seventeenth century it as the gateway to Mexico City.
‍
The project not only allowed the custody of the parliamentary memory of our country but would also give a new life’s purpose to one of the oldest and most emblematic buildings in Mexico City.

To consider a document with the historical character, not only responds to a criterion of time, but it must also pass a documentary evaluation and conservation periods in processing and conservation archive, before it is transferred to the Historical Archive and becomes part of the national cultural heritage

The General Library of the H. Congress of the Union was born from an initiative presented before the plenary session of the Chamber of Deputies on August 24, 1935, with the aim that its services were also for the benefit of society.

On November 12 of the same year, the proposal was expanded by Deputies Luis Mora Tovar, Demetrio Bolaños Espinosa and Carlos A. Calderón, who presented the initiative to install and reorganize the Public Library of the H.

Since then, the library has been open public, and is located on Tacuba Street 29, in the Mexico City Historical Downtown (Zocalo)
