Travellers consider a good book the most essential item to take on holiday, according to a survey by flight search engine Skyscanner.
A poll on the company’s website found that nearly a quarter (24 per cent) of people consider books a crucial part of a holiday, followed by an mp3 player (22 per cent).
Perfume or deodorant and a laptop or personal digital assistant also appear important to travellers, gaining 14 per cent and ten per cent of the vote respectively.
Rob Innes, head of marketing at Skyscanner, said: "The humble paperback is the ultimate travel accessory. It’s a low cost, no-tech form of entertainment that you can take anywhere – from the beach to the bar. You don’t need to worry about books getting lost, stolen or damaged, or that your battery will die mid-flight.
"Books can also be exchanged with fellow travellers, giving you some entertainment currency. iPods and laptops are great for music and films but their high value means they can be more of a burden when travelling."
The flight search engine recently revealed the destinations that customers have been showing an interest in ahead of the Easter holidays, with London taking the top spot.
Rome also appeared in the top ten, along with Barcelona, Paris and Dublin.
