In an increasingly digital world, libraries are surplus to requirements, right? According to the Voices for the Library campaign, more than 10 per cent of the UK¡¯s public libraries are currently at risk of closure by their local authority, and hundreds have been shut down in the past two years alone.

For universities, however, both modern and historic libraries are at the heart of campus life. A new book, (published this month by ROADS Publishing), has collected 44 images of the most iconic library buildings, and it includes some inspiring photographs from some of the world¡¯s best known higher education institutions.

From the cutting edge Law Library at the University of Zurich, opened in 2004, to the Trinity College Library in Dublin, which has been used by scholars since the 16th century, the images offer a glimpse into the world of university library design, and the many different forms that they can take.

1. The Law Library at the University of Zurich

The Law Library of the University of Zurich was designed by Spanish architect Santiago Calatrava, who also designed the Milwaukee Art Museum in the US and the Peace Bridge in Calgary, Canada.

3. The Royal Library at the University of Copenhagen

This photograph is taken from inside the atrium of The Royal Library at the University of Copenhagen, also called ¡°the Black Diamond¡± because of its black granite exterior. It is a modern extension to the old Royal Library building on the waterfront in Copenhagen.

Designed by Danish architects Schmidt Hammer Lassen, the building opened its doors in 1999 and in addition to the library, also houses an auditorium.

4. Trinity College Library in Dublin

The library at Trinity College in Dublin is the largest in Ireland, and dates back to the establishment of the College in 1592. It has more than 6 million printed volumes.
