If you put all the books you own on the street outside your house, you might expect them to disappear in a trice. But one man in Manila tried it - and found that his collection grew.
Hernando Guanlao is a sprightly man in his early 60s, with one abiding passion - books.
They're his pride and joy, which is just as well because, whether he likes it or not, they seem to be taking over his house.
Guanlao, known by his nickname Nanie, has set up an informal library outside his home in central Manila, to encourage his local community to share his joy of reading.
