The very interesting blog "Curious Expeditions" has a must-see post containing a large number of images of the most beautiful libraries from around the world. Here is the Strahov Theological Hall, in Prague:

Here are more images of that amazing room, from a Flickr page.
One library I would add to the Curious Expeditions compendium is the library of the Brooklyn Historical Society (completed 1881, George B. Post, architect), one of the most beautiful rooms in New York:

One more American library, this one included at Curious Expeditions:

That's the Peabody Library (Edmund G. Lind, architect, 1878) in Baltimore. It's one of the most special places in this country. Who out there has ever designed a library? Let us post pictures of it!
I just stumbled across this site, absolutely love it; I am very much inspired by Classical Architecture.
After seeing the photo of the library of the Brooklyn Historical Society, I realised that I had seen something strikingly similar before! The College Library of my school, Eton College next to Windsor in England looks so much like it! Unfortunately I cannot find any images on the internet for a comparison...
Thanks for the site!

I wish I had a photograph of the Divinity Library at Yale. It has the same spacious and balanced feeling as the Brooklyn library above. Years ago, I trudged up Prospect Street just to imbibe the beauty of that library which I considered the perfect place to study or daydream. Old, missionary biographies surrounded me. A fireplace, rarely lit, was centrally placed at one end. Whispering "divines" occasionally shuffled past.
In many ways, it resembled an apse, not a library -- more church than state.
What ever happened to fireplaces in libraries? Their flickering light and occasional crackling sound created a perfect ambiance for thoughtful reading.
