The World's Twenty-Five Most Modern Libraries
From BestCollegesOnline.com, a list of the 'twenty-five most modern libraries' with links to each.

Among the top 25 are the national libraries of Australia, Britain, France, Denmark, Czech Republic, Japan and the LOC, and a good number of large metropolitan libraries.
