LONDON - Legions of Harry Potter fans waiting eagerly for the boy wizard's fifth adventure will have to make do, for now, with revisiting earlier installments.

No release date for Harry Potter and the Order of the Phoenix has been set, the office of Christopher Little, author J.K. Rowling's agent, said this week.

Harry Potter and the Chamber of Secrets, the second movie in the series, opened Friday.

The first Harry Potter book, published in 1997, was Harry Potter and the Philosopher's Stone - released in the United States as Harry Potter and the Sorcerer's Stone. The second and third volumes followed over the next two years, and the fourth, Harry Potter and the Goblet of Fire, appeared in July 2000.

A year ago, Ms. Rowling wrote a letter to The Scotsman newspaper insisting she was not suffering from writer's block and that there had been no intention of publishing book five in 2001.

In September, after a U.S. federal court rejected claims by an American author that Ms. Rowling had stolen ideas from her own children's books, Ms. Rowling said the stress of the lawsuit had hindered her progress on the fifth book.

Ms. Rowling said in a British Broadcasting Corp. television interview that much of Harry Potter and the Order of the Phoenix, was written, but declined to say when it would be ready for publication.

"There's a lot of book done. . . . I know a lot of fans will say, `Just to give it to us.' But I'm a perfectionist and I want a bit more of a tweak."
