There is a special way the library grows. It is a legal deposit library. This means it receives copies of all books made in the United Kingdom and Ireland. It also gets many books from other places. This rule helps the library keep a record of what people write. The library adds about three million new items every single year. 
The library has a very long history. It was officially created on July 1, 1973. Before this, the national library was part of the British Museum. The library grew by joining with smaller groups. It took over the National Central Library and other collections. Some items came from very famous people in the past. For example, Sir Hans Sloane donated his books and natural history items. 
The main building is in London near St Pancras station. 
Today, the library also works in the digital world. In 2005, it started the UK Web Archive project. This project saves websites to keep a "digital memory" of the nation. The library also saves electronic books. Even though the internet changes fast, the library tries to preserve it. In 2023, the library faced a hard job when a cyber attack hit its website. This made many services hard to reach for a while. However, the library continues to work on growing and protecting its many treasures.
The British Library serves as the national library of the United Kingdom. 

The library grows through a specific process called legal deposit. Under the Copyright Act 1911, the library is entitled to receive free copies of every item published in Britain. It is the only library that must receive these copies automatically. This system ensures a complete record of the nation's written history. The library also receives books published in Ireland. 
The history of these collections stretches back many centuries. The core of the library is built on "foundation collections" from the 18th century. These include the library of Sir Hans Sloane, who died in 1753. His donation helped form the British Museum. Other important pieces came from Robert Harley and Sir Robert Cotton. 
The British Library was officially created on July 1, 1973. Before this, the national library was part of the British Museum. Over time, the library grew by absorbing several other organizations. It took over the National Central Library and the National Lending Library for Science and Technology. In 1982, it became responsible for the India Office Library and Records. In 1983, it added the National Sound Archive. 
The main purpose-built building is located in London near St Pancras station. 
Because the collection is so vast, the library uses multiple sites. Much of the material is stored at an additional facility near Boston Spa in Yorkshire. This storage building cost £26 million to complete. It has a capacity for seven million items. Inside, robots retrieve items from 162.7 miles of temperature-controlled storage space. 
In the modern era, the library has expanded into the digital world. In 2005, it began the UK Web Archive project to preserve websites. The library also uses a Digital Library System to collect web data automatically. This helps preserve the nation's "digital memory."
The library continues to plan for the future. In March 2025, it announced a £1.1 billion expansion project. This project is a partnership with Mitsui Fudosan. It aims to add 100,000 square feet of space for research and cultural activities. This growth will be supported by new commercial and retail areas. The library remains a growing, changing home for the world's knowledge.
