BookScape is an interesting concept for a online library archive.  It was created by Michael Chang of Yahoo's Design Innovation Team.  The project focuses on creating an interface that allows access to digital versions of 2600 illustrated children's books. Images of the scanned books are arranged alphabetically.  Dynamic resampling is used to efficiently show all the images at once in one zoomable space.  Zooming out allows quick navigation of the entire collection.  Zooming in gives you more finite navigation control.  This project reminds me a bit of some of the thinking behind Microsoft's amazing Photosynth that I wrote about earlier this year.
