If you paid attention to the circumstances you would notice that she is not criticizing the creation of fansites and encyclopedias but rather the use of said media FOR PROFIT. As for the Lord of the Rings encyclopedias, the Lord of the Rings is in the public domain because the property rights have expired; this is NOT the case with Harry Potter.

Mr Corr, "you have more money than me. Please spare a few hundred and send it to me." That line of thought doesn't seem so good now, does it?
It's her money: she (not you) decides.

Ed Moran, Torquay,

I am not seeing this as a lost of potential profit to Ms Rowling but more as another person or company exploiting her work. Harry Potter belongs to her and is not public domain. Why should her let someone capitalize on her creation?

As ones net worth approaches and then surpasses the $1 Billion mark, all sorts of things become imaginable. Just ask any billionaire. The 'sense' of it all makes little difference.

Money and fame appear to have gone to the head of JK Rowling, and now she is attacking her own fans who created the websites out of their love for her books, websites which she has admitted to using for when writing her series. The book which is derived from the web-based encylopedia is not going to be a competitor for her own book, and what she is doing is mean-spirited and ungenerous to her fans who have worked on those websites out of love for a long time. She should take a look at herself and see what she has become - a soulless corporate entity who sues everyone in sight for the slightest infringement.

hazh, Oxford,

There are numerous Lord of The Rings encyclopaedias and a large number relating to Sherlock Holmes to name just two.

Come off it Ms Rowling, your books are in the public domain and anyone can write books about them without your permission.

If you're so concerned about charities give them the money you're about to pay your lawyers and shut up.

Roger Tilbury, worthing,

J. K. Rowling has every right to fight to protect her intellectual-property!!! She created this world that we all love and therefore only she can write a definitive Harry Potter encyclopaedia, which will provide a true account of the characters to satisfy all Harry Potter fans who just want more and more!!! The fans and more importantly needy causes are the real winners here! J.K I hope you rein victorious!

Paula Falvey, Cork, Ireland

She is the creator of Harry Potter and should have a say in anything and everything having to do with Harry Potter. Regardless of how much money she has, she is willing to write books for charity and that act should not be destroyed by someone seeking financial gain.

Oh dear me, Ms Rowling, surely you could spare a few million of your profits from the series of novels. You have more than enough to go round the charities you want to donate to. You're richer than the Queen for Dumbledore's sake.

By all means write a companion encyclopedia, but unauthorised guides written by fans are common-place. Have you seen how many Da Vinci Code companions there are in bookshops these days?

Time for you to leave Hogwarts and join the real world!

Andrew Corr, Burton On Trent, England

i love harry potter its great!!!!!!!!!!!!!!!!!!!!!

While I look up to Rowling for her story telling ability and the Harry Potter series as a whole, there wouldn't be a need for a encyclopedia had she concluded the seventh book a little better.
