A system of international exchanges was begun by the Institution in 1850 for the 

 free interchange of scientific publications between institutions and investigators in the 

 United States and those in foreign lands. Since 1867 this has been the official channel 

 for the transmission of United States documents to foreign governments in exchange 

 for their official publications. Ref.: History of the Smithsonian exchanges, by G. H.
