 While he was able to reorganize important services within the institution and create an influential monthly illustrated magazine on Brazilian history , his tenure was marked by strong opposition by the leaders of the union of the library's employees, some of whom were deprived of irregular benefits granted by previous administrations, which were disallowed by Corrêa do Lago.In mid 2005, during a three-month strike by the public servants of the Ministry of Culture (which forced the National Library to be closed during that entire period), a theft occurred of rare items including photographs, prints and drawings (which were later mostly recovered).This crime was perpetrated by a gang that has since been jailed and had pillaged several Brazilian cultural institutions in the early 2000s.
