President Manuel Roxas signed Executive Order No. 94, converting the National Library into an office under the Office of the President called the Bureau of Public Libraries. The name change was done reportedly out of a sense of national shame as a result of World War II, with Roxas preferring to emphasize the library's administrative responsibilities over its cultural and historical functions. Although the library was offered its original headquarters in the newly-rebuilt Legislative Building, the newly convened Congress of the Philippines forced it to relocate to the old Legislative Building at the corner of Lepanto (now Loyola) and P. Paredes Streets in Sampaloc, near the current campus of the University of the East. The Circulation Division, originally meant to cater to the residents of the city of Manila, was abolished in 1955 after it was determined that the city's residents were already adequately served by the four libraries under the supervision of the Manila city government. That same year, it was forced to relocate to the Arlegui Mansion in San Miguel, then occupied by the Department of Foreign Affairs. During this time, much of the library's Filipiniana collection was gradually restored. In 1953, two folders of Rizaliana (works pertaining to José Rizal) previously in the possession of a private Spanish citizen which contained, among others, Rizal's transcript of records, a letter from his mother, Teodora Alonso, and a letter from his wife, Josephine Bracken, were returned by the Spanish government as a gesture of friendship and goodwill. Likewise, the 400,000-piece Philippine Revolutionary Papers (PRP), also known as the Philippine Insurgent Records (PIR), were returned by the United States in 1957. After many moves throughout its history, the National Library finally moved to its present location on June 19, 1961, in commemoration of the 100th birthday of José Rizal. It was renamed back to the National Library on June 18, 1964, by virtue of Republic Act No. 3873. Contemporary history (1964–) Although no major changes occurred in the National Library immediately after its relocation, two significant events took place in the 1970s: first, the issuance of Presidential Decree No. 812 on October 18, 1975, which allowed the National Library to exercise the right of legal deposit, and second, the resumption of work on the Philippine National Bibliography (PNB) which had been suspended since 1941. For this purpose, the library acquired its first mainframe computer and likewise trained library staff in
