From the 4,500 year old Ebla tablets found in one of the earliest Syrian kingdoms, to the legendary libraries at Pergamum, the great Library of Alexandria, and what is believed to be the world’s oldest library, the Library of Ashurbanipal in modern-day Iraq, humankind has been on a constant quest for knowledge.

Like other icons of culture, such as the world’s biggest theatres or the tallest statues in the world, libraries are often seen as a testament to national endeavour. Here are the world’s biggest libraries, including the largest library in the world, as defined by the number of items.

The Kungliga Biblioteket, or ‘Royal Library’ was established in 1661 from the collection of King Gustav Vasa. Today the library is home to books, posters, photographs, newspapers and manuscripts – some of which date back over a thousand years – as well as around 10 million hours of audio-visual material.

A contender for the title of biggest library in the world, the National Library of Spain was established in 1712 by King Philip V and is located in a beautiful building on the Paseo de Recoletos. As well as books and printed and graphic materials, over 1,000 staff look after 600,000 audio recordings, over half a million music scores and 500,000 maps. The collection includes the manuscript of the 900 year old El Cantar de mio Cid, the oldest preserved Castillian epic poem.

The 23m x 90m Rose Reading Room is one of the world’s great library halls. Amongst the millions of books, manuscripts and maps, the collection includes Thomas Jefferson’s handwritten copy of the Declaration of Independence, a lock of Beethoven’s hair and the desk from where Charles Dickens wrote Hard Times.

Library of Congress

A contender not just for the title of world’s biggest library, but also for the title of the most beautiful library in the world. The Library of Congress was established in April 1800 primarily to answer research inquiries raised by members of Congress. While it is available to the public, only its 3,105 employees and the upper echelons of government may check books out.

In addition to the 40 million books, 3.6 million audio recordings, 15 million photographs, five million maps, eight million pieces of sheet music and 72 million manuscripts, it is home to the largest collection of fifteenth century books in the Western Hemisphere.

Some of the prized works held by the British Library include an original copy of the epic poem Beowulf, the Lindisfarne Gospels, a very early copy of Chaucer’s Canterbury Tales, Captain James Cook’s journal, two original copies of the Magna Carta, an illustrated manuscript of Dante’s Divine Comedy, da Vinci’s Arundel Codex, five copies of Shakespeare’s First Folio of plays from 1623, one of 27 surviving copies of Abraham Lincoln’s Emancipation Proclamation and original, handwritten lyrics of Yesterday, A Hard Day’s Night, Help! and Strawberry Fields Forever by The Beatles.
