Little bookworms from all over Northern Ireland dressed up as their favourite characters for World Book Day yesterday.
The international celebration aims to turn millions of kids into millions of readers.
One was Coleraine boy Oliver Dickey.
He was diagnosed with a form of cerebral palsy when he was 18 months old.
Big-hearted Ulster folk raised cash to take Oliver to America for surgery to help him walk, and yesterday the youngster dressed up as his favourite character Stick Man - doing his bit for the books he loves.
And Education Minister John O'Dowd, about to step down from his post, chose World Book Day to open a new library at St Patrick's Primary School in Cullyhanna.
"Reading is something that I encourage all young people to get involved with and enjoy," the minister told pupils and parents on his visit to the south Armagh school.
