大英图书馆是英国的知识宝库，也是全世界最大的学术图书馆之一，它位于伦敦的圣潘克拉斯。其藏品数量超过 2 亿件，涉及四百多种语言，堪称世界之最。
The British Library has a copy of every book ever published in the UK.
Or at least, it should have.
If you're in the UK and you publish a book, magazine, or newspaper, then by law you have to send a copy here.
A lot of countries around the world have similar laws and similar libraries.
The rules for what must be sent here were pretty simple to understand... until the end of the 20th century, when the web came along, and suddenly, books and publishing weren't quite as easy to define.
In the print world, we collect everything.
So anything you can imagine, whether that is an NHS information leaflet, local magazine, or the most expensive journal that you can imagine.
Or those beautiful art books that cost thousands of pounds.
Those kids' magazines that you see on the shelves in Tesco's with the plastic toys on.
We collect all of those.
