'A remarkable time capsule': The enchanting history of Oxford University's 750-year-old medieval library

Predating the Aztec Empire, Merton College Library in Oxford has been used by everyone from celebrated 14th-Century mathematicians to JRR Tolkien. In an exclusive interview with the BBC for its 750th birthday, its librarian describes what makes it so special.

At Merton College in Oxford, there is an antique chest. In the Middle Ages, three key-holders had to be summoned to reveal the riches within. But this treasure wasn't gold or jewels. It was books.

Such strict security may sound overly cautious for mere parchment. But in an era before the printing press, books were a valuable commodity. They could take months to produce, as the entire text had to be painstakingly written out by hand. So, just as universities solicit cash from their alumni today, Merton College insisted its 13th-Century fellows donated books.

 
There's no single definition of a library – Prof Teresa Webber
The Archbishop of Canterbury issued a decree in 1276 introducing this requirement, which marked the beginning of the library at Merton College. It has been running continuously ever since. To put that length of time in context, Merton's library predates the Aztec Empire. Its unbroken history stretches from before the Black Death to beyond the Covid-19 pandemic. And its users have encompassed everyone from famous 14th-Century mathematicians to Lord of the Rings author JRR Tolkien.
 
This month marks the library's 750th anniversary. It's a major milestone. But Merton's extraordinary lifespan has been recognised since the Victoria era, when it was routinely described as the oldest library in England.

In the 20th Century, writers like Rudyard Kipling and John Buchan referenced it in works of historical fiction, bolstering its reputation as a particularly venerable library. As the cultural recognition of "the famous Merton Library" grew, claims about its longevity became exaggerated. Some overzealous Oxonians even declared it the oldest library in the world.

The origins of the historic library
Historians today are more careful about making such bold declarations. "It's a complicated question," says Prof Teresa Webber from the University of Cambridge. "There's no single definition of a library. And there were all sorts of stages in the development of what we think of today as a library."
