Chain bookstores will do the same. Borders stores nationwide will host a party, called Grand Hallows Ball. In Silver Spring, Borders will transform Ellsworth Drive into Diagon Alley, a fictional shopping hub in the books, for the 9 p.m. party. And competitor Barnes & Noble in Alexandria will have a Midnight Magic Party. Both will feature costume contests, entertainers and games.
Booksellers also are selling Potter-themed merchandise, hoping to attract customers. Borders is selling everything from wall scrolls and games to such Potter food products as Bertie Bott’s Every Flavor Beans. Barnes & Noble is selling items like baseball hats, T-shirts and chess sets.
Sales of the merchandise have been strong, with the book’s release only 10 days from the fifth movie, said Ann Binkley, director of public relations for Borders Group.
“You’re getting double media exposure,” Mrs. Binkley said. “It’s no surprise that they’re selling so well. People are in ‘Harry Potter’ mania right now.”
There won’t be any Potter parties at Kramerbooks & Afterwords Cafe & Grill in the District, said Travis Niemann, bookseller at the store. No midnight parties and certainly no costumes.
“In the more suburban stores, people are going crazy and dressing up,” Mr. Niemann said. “We’re just going to sell them to whoever wants them.”
The series has proved immensely popular for Scholastic and its British publisher Bloomsbury Publishing Plc. Together, the two have sold more than 350 million copies of the first six books, contributing up to $800 million in revenue for Scholastic, said Drew Crum, an analyst with Stifel, Nicolaus & Co.
But the end of the series ends Scholastic’s money maker one that has been a distraction from other parts of the company’s business, Mr. Crum said.
“There’s a lot of build up, a lot of momentum ahead of the publication date, but then you have to fall back on the legacy business ex-‘Harry Potter,’ ” he said. “And quite frankly, the earnings power of the company ex-‘Harry Potter’ has not been great in the last several years.”
Each book in the series has had predictable success, but it is not any different from other best-sellers, Mrs. Dawson said. The series has, however, increased focus on the often-successful children’s fantasy genre.
“[“Harry Potter”] is not that much of a phenomenon,” Mrs. Dawson said. “ ’Harry Potter’ is essentially fluke, but it is a seven-book fluke.”
Scholastic’s focus on Potter has distracted the company from its troubled direct-to-home business, which markets to prekindergarten children, Mr. Crum said. Problems in that business have caused a loss of about $20 million per year while a break-even year for that segment implies a huge 30 to 35 cent swing on earnings, he said.
That focus on “Harry Potter” also causes more resources go toward the series instead of other parts of the children’s book division, Mr. Crum said.
“If you look at children’s book performance ex-‘Harry Potter,’ it’s better in years in which they don’t publish a new ‘Harry Potter’ book,” Mr. Crum said.
Still, Potter backlist sales will continue to generate between $5 and $10 million in revenue annually for the company, Mr. Crum said. And its relationship with author J.K. Rowling could produce future blockbusters, since the author still wants to write, he added.
