In 1907, The Barcelona Museums Board creates the Special Library Committee. Two aspects should be mentioned about this period: on one hand the important efforts that Josep Puig i Cadafalch and Joaquim Folch i Torres made to consolidate the Library, and on the other the notable enrichment of the collection with the donation, in 1914, of the Vidal i Quadras Library, the Riquer acquisition in 1921, and the donation by Eduard Toda in 1931. In 1933, the Library moved to the Poble Espanyol, to premises created around the International Exhibition of 1929.

1913 Joaquim Folch i Torres wins the post of Museums Board librarian

The post of librarian is taken by Joaquim Folch i Torres after presenting a paper and winning the competition. He gets down to bringing the work begun by Puig i Cadafalch up to date. Joaquim Folch i Torres, museologist, historian and art critic, is subsequently director-general of the Art Museums of Barcelona from 1920 to 1926 and from 1930 to 1939.
