Deep within the warehouse capital of the country lies a literature lover's treasure trove.
Hidden from view, among the "mega-sheds" and supply chain businesses of Northamptonshire, there is no hint of the historical wonders inside.
But this non-descript warehouse on the outskirts of Rushden is home to the Penguin Random House UK Library and Archive.
It features 1.5 million books by some of the biggest names in literature, including Agatha Christie, Ernest Hemingway, Roald Dahl and Jilly Cooper, as well as many other documents relating to the world-famous publisher, now celebrating its 90th birthday.
"It's pretty overwhelming. I love it, though," says Nicki Carter, senior library and archive assistant, who joined the collection seven years ago.
