Friday, September 26th, 2008

Maps and newspapers, because they're rich in graphic information, benefit greatly from a zooming and panning interface.

Looking at Google Newspapers has got me thinking that the same sort of zooming-panning interface that's used in that, and in Google Maps, could also be used for viewing books.

Google Books vs DjVu in Internet Archive

Shown below are the "intro" pages for the book in the 2 systems. The clear advantage of ...
