Guinness World Record: Woman collects Doctor Who memorabilia
But you don't need a Tardis to go far to find Guinness World Record holder Lily Connors, 19, who has the largest collection of memorabilia.
Lily, from Swansea, was just 12 when she was awarded the record in 2016 - and had held it ever since.
"I just love everything about it," said Lily, who has the ultimate goal of being an extra on the show.
For items to qualify they must be official BBC merchandise with no duplicates.
The super fan from Swansea has a total of 6,641 individual items that qualify but her full collection exceeds more than 10,000 pieces.
"It wasn't until I was eight that I really start to collect," she said.
"I'd spend all my pocket money on it. I used to make charm bracelets, costume jewellery, wind chimes, and then sell all of them on boot sales. All the money I could save I'd spend on Doctor Who.
"I pick the memorabilia up from anywhere; shops, car boot sales, on-line. You can pick Doctor who up anywhere. And if I see it, I pick it up."
