As part of the HCA celebration the British Library has a special exhibit in London.

This is a new-style exhibition for the British Library. Interactive exhibits complement the more traditional historical material to mix word and play, reality and magic. Within a soundscape inspired by Andersen's stories, puppets, pulleys, projections and paper-cuts bring his characters to life. Visitors can perform their own fairytales, go under water with the Little Mermaid and find the Snow Queen herself. There are also live performances for families with young children.

There is a contest and splendid HCA e-cards on the website too.
