Women around the world are today celebrating International Women's Day 2017 (IWD) by hiding feminist books in plain sight in public places for people to find and enjoy.

People in the UK, United Arab Emirates, New Zealand, Singapore, France, Italy, Germany and Hungary and Slovakia have been posting about their book-hiding endeavours.

Emma Watson tweeted about the global project, which is being organised in collaboration with The Book Fairies as part of her feminist bookclub initiative Our Shared Shelf's collaboration with Books on the Underground.

Watson took to the London Underground in late 2016 to hide copies of Maya Angelou's Mom & Me & Mom. But Watson has taken the project to a global scale to mark IWD.

Readers who find the books are encouraged to return the books to a public place for another person to enjoy.
