When the old Palacio de Gobierno was demolished in 1938, a mass of papers and volumes were discovered and saved. They turned out to be the heart of the colonial archive of the Lima Tribunal of the Consulado (or Merchant’s Guild) and represented a substantial portion of the colonial Hacienda, or treasury, papers of Lima as well. An archive, the Archivo Histórico de Comercio y Hacienda, was created (and opened in 1944) for the express purpose of housing these documents and its first director, Frederico Schwab, was entrusted with the organization and cataloguing of this valuable collection. Schwab and Luis Felipe Muro Arias’ Catàlogo de la Sección Colonial del Archivo Histórico del Ministerio de Hacienda was published in Lima in 1944 and listed all of the major documentation held by the new archive relative to the colonial affairs of the Consulado and the Real Hacienda. A few years later Robert Sidney Smith, another scholar to reach and work this rich depisitory in its early years, transcribed the original index to the archive created by the Consulado to house its papers in the late eighteenth century. This work, El Indice del Archivo del Tribunal del Consulado de Lima, appeared in 1948 with an excellent preface to the history of the collection by Schwab and a valuable introduction to the Lima Consulado prepared by Smith himself. Since then, scholars such as the Peruvian Manuel Moreyra y Paz-Soldan and the Frenchwoman Marie Helmer have been able to take advantage of this great collection because of the pioneering work of Schwab, Smith, and their colleagues. The archive has since lost its autonomy and is now incorporated into the Archivo Nacional, which was a logical step in centralization since both archives are located in the Palacio de Justicia in Lima.
