Find out key stats around our collections, buildings and users.
- Our collections include over 170 million items from almost every language and faith group.
- Together, they occupy over 746km of total shelving – equivalent to the distance from London to Aberdeen, and this is growing an extra 8km every year. Meanwhile our digital collections amount to over 1 petabyte – equivalent to almost 3.5 years of non-stop HD-quality video footage.
- We receive a copy of every publication produced in the UK and Ireland through legal deposit. Last year we received over 500,000 printed and digital items and over 100 terabytes from the UK web domain.
- If you see five items each day, it would take you over 80,000 years to see the whole of the collection.
- Since it launched in 2004, the Endangered Archives Programme has preserved over a million manuscripts, documents, photographs, recordings and other at-risk material.
In our collections you can find:
- material ranging from Magna Carta and Leonardo da Vinci’s Notebook to today's newspapers and websites
- 13.5 million printed books and e-books
- 310,000 manuscript volumes: from Jane Austen to James Joyce; Handel to the Beatles

- The building has a total floor area of over 112,000 sq metres spread over 14 floors: nine above ground, five below. The basement stores run 24 metres below ground – the equivalent of an eight storey building – and reach as deep as the Victoria line which runs alongside them.
- Designed by Sir Colin St John (‘Sandy’) Wilson, our St Pancras building was awarded Grade I listed building status in August 2015.
