NEW YORK — J.K. Rowling’s next book is for adults, but she will be on hand this fall to help promote a new club for kids, the Harry Potter Reading Club.

Scholastic Inc. announced Tuesday that Rowling will participate in a live webcast at noon on Oct. 11 from her hometown of Edinburgh, Scotland, taking pre-submitted questions from her young fans. The discussion will take place on scholastic.com/hpreadingclub, the website for an online Potter club launched Tuesday by Scholastic.

The club is designed for schools and libraries and parents. It will include discussion guides, a glossary, interactive features and information on community events. Rowling will contribute original commentary. She has a novel for grown-ups out in September called “The Casual Vacancy.”

Olympic coverage stays strong for NBC

NEW YORK — NBC’s London Olympic coverage has topped Beijing for the fourth night in a row.

The Nielsen company estimated that Monday night’s prime-time coverage was seen by 31.6 million viewers, up from the 30.2 million who watched the first Monday of competition in Beijing four years ago.

Nielsen’s overnight measurement of the nation’s largest cities showed NBC’s ratings down 5 percent from the 2008 Games. But Nielsen’s viewership estimate is the more definitive number, a measurement based on Nielsen meters all across the country.
