JK Rowling speaks in 1997 about how she got Harry Potter published

It's 20 years since Harry Potter and the Philosopher's Stone hit the shops.

It was the first in a series which ended up selling millions of copies and being turned into blockbuster movies.

Here, the author tells the BBC how she couldn't afford to photocopy the manuscript, so sent it to a list of publishers one by one.
