The New York Public Library has developed a free App for the iPad called Biblion: the boundless library. It is a development of their print magazine into multimedia, and it is done superbly. This first issue focuses on the World Fair 1939-40. It is a wonderful mix of images, text, film and audio.
It really has the quality of visiting an official exhibition - plus the added digitised notes and letters give every visitor a hint of the background involved in working in archives and special collections.
Alexis Madrigal at the Atlantic wrote a good review.
This is a wonderful way of sharing the library's collections with the world. Maybe we could do this for our North Queensland collection?
