A Belfast-born writer has made it on to a list of Britain's top 100 favourite books.
The Lion, the Witch and the Wardrobe was first published in 1950
CS Lewis was nominated for his children's classic, The Lion, the Witch and the Wardrobe.
More than 140,000 people voted in the television and online poll.
All four Harry Potter books were nominated, while children's books, including Anna Sewell's Black Beauty and AA Milne's Winnie The Pooh, made up a third of the titles picked by the public.
Charles Dickens and Terry Pratchett were the most nominated authors, each with five books on the list.
Jane Root, controller of BBC Two, said there had been a "fantastic" response to the vote.
"On our website over 14,000 messages were posted by people engaging in heated, passionate and funny debates about why their book was the best choice.
"We hope this kind of contagious enthusiasm will spread over the summer and thousands of people will join book groups to discuss, debate and share the experience of books."
Later in the year, the top 20 will be championed by celebrity fans and the public will vote to decide the nation's favourite.
Clive Staples Lewis was born in Belfast and became a professor of Medieval and Renaissance English at Oxford, where his contemporaries included JRR Tolkien.

The Lion, the Witch and the Wardrobe was first published in 1950, before the six other Narnia books.
In 2000, parents, teachers and librarians selected it as the most influential children's book of the 20th Century.
Lewis was inspired by religious themes throughout his work.
The Narnia stories are an allegory of the life of Christ.
In the books, the character of Aslan, an inspiring lion, represents Christ, who is persecuted but eventually triumphs.
