More words have probably been written about Jo Rowling than the content of all
the Harry Potter books put together! Much of it is about her being a single parent
who wrote the first Harry Potter novel in a café whilst her small daughter was
asleep next to her.
Rather than repeat the story here, you can see full details - and photos - on
the Harry Potter pages on the official "Bloomsbury" site - Bloomsbury are the
original publishers of Harry Potter's books. You can get lots of useful info there,
though the pages on their site are sometimes a bit slow to load. The address is
http://www.bloomsbury.com/harrypotter/.
You can also join their "Bloomsbury Web Club" to get advance information on each
new Harry Potter book - this should tell you when any further editions
will be available - and also an e-mail birthday card signed by J.K. Rowling.
