Abstract
The Mexican National Newspaper Archive (Hemeroteca), together with the National Library depends upon the Institute of Bibliographical Researches (IIB) of the National Autonomous University of México (UNAM), and has had several places to keep and house its valuable hemerographic collection: from the choir and the chapel of the Third Order of the ex-convent of San Agustín, the church of San Pedro and San Pablo, up to the modern building in the IIB.
