The overcrowded conditions of the library was one of the reasons why the RIBA moved from 9 Conduit Street (where it had been since 1859) to larger premises at 66 Portland Place in 1934. The library remained open throughout World War II and was able to shelter the archives of Modernist architect Adolf Loos during the war. The library is based at two public sites: the Reading Room at the RIBA's headquarters, 66 Portland Place, London; and the RIBA Architecture Study Rooms in the Henry Cole Wing of the V&A. The Reading Room, designed by the building's architect George Grey Wornum and his wife Miriam, retains its original 1934 Art Deco interior with open bookshelves, original furniture and double-height central space. The study rooms, opened in 2004, were designed by Wright & Wright Architects. The library is funded entirely by the RIBA but it is open to the public without charge. It operates a free learning programme aimed
