The celebrations by book lovers are well under way as World Book Day takes place across the country.

An annual event, the day encourages people to dress up as their favourite book characters and indulge in all things novel related, including receiving book tokens.

In its 19th year, we also took a look back at the World Book Days celebrated in west London in the past.

From Harry Potter characters, to aliens, Mr Men and Little Miss figures and even animals, west London schools have dressed to impress as they share their favourite parts of books.

But that's not all that happens today. In a push to remind people how reading can improve all kinds of skills such as empathy, memory and patience, World Book Day organisers have left a trail of ways you could get your hands on free books.

Where can I get hold of a free book?

Books for London is trying to get a book drop off point in as many tube and train stations as possible, while Books on the Underground lets people drop books on public transport with a sticker on the front so they are not removed by staff (you can get the stickers sent to you free if you want to drop something off yourself).

If you're looking for something specific, Read It Swap It lets you find people who've already read the book and would like to swap it, you swap emails then post the books to each other - or potentially drop them off somewhere nearby if you live near each other.

Other ways to get hold of a free book include downloading free e-books - and you don't have to own a kindle as there are copies for those with smart phones too.

Have you dressed up this year? Send in your photographs to or tweet @getwestlondon and we will add them to our gallery!
