NYPL refers to Biblion as The Boundless Library, taking the stacks of the famous library to anyone in the world with an iPad (a web version is apparently in the works). Here you see the "cover" of the electronic magazine, showing links to some stories you might want to browse.
This unique browser can be flicked up or down, and touching a specific essay brings you into a screen showing details of that story. The colored bars show the type of content contained on each page -- audio/video, featured images, documents, or "connections."
Newspaper clippings from around the time of the Fair also focus on what was taking place -- this article talked quite a bit about television as "one of the most important things to emerge" from the Fair. It has made quite an impact since 1939...
Want to know how much it would have cost you to eat at the Fair? A look at the "American Drinks and Sandwiches" menu at Le Restaurant Français shows that by today's standard, it was very cheap. 75¢ for an imported French tin of Paté de Foie Gras, and a glass of French wine for just 40¢ more.
This section deals with the records of the Fair and preservation for the future. If Biblion continues to put the NYPL's stacks on display in this electronic format, they'll do a great service for the human race.
