After 244 years, the Encyclopaedia Britannica is going out of print.
Those coolly authoritative, gold-lettered reference books that were once sold door-to-door by a fleet of traveling salesmen and displayed as proud fixtures in American homes will be discontinued, company executives said.
In an acknowledgment of the realities of the digital age — and of competition from the Web site Wikipedia — Encyclopaedia Britannica will focus primarily on its online encyclopedias and educational curriculum for schools. The last print version is the 32-volume 2010 edition, which weighs 129 pounds and includes new entries on global warming and the Human Genome Project.
“It’s a rite of passage in this new era,” Jorge Cauz, the president of Encyclopaedia Britannica Inc., a company based in Chicago, said in an interview. “Some people will feel sad about it and nostalgic about it. But we have a better tool now. The Web site is continuously updated, it’s much more expansive and it has multimedia.”
In the 1950s, having the Encyclopaedia Britannica on the bookshelf was akin to a station wagon in the garage or a black-and-white Zenith in the den, a possession coveted for its usefulness and as a goalpost for an aspirational middle class. Buying a set was often a financial stretch, and many families had to pay for it in monthly installments.
But in recent years, print reference books have been almost completely overtaken by the Internet and its vast spread of resources, including specialized Web sites and the hugely popular — and free — online encyclopedia Wikipedia.
Since it was started 11 years ago, Wikipedia has moved a long way toward replacing the authority of experts with the wisdom of the crowds. The site is now written and edited by tens of thousands of contributors around the world, and it has been gradually accepted as a largely accurate and comprehensive source, even by many scholars and academics.
Wikipedia also regularly meets the 21st-century mandate of providing instantly updated material. And it has nearly four million articles in English, including some on pop culture topics that would not be considered worthy of a mention in the Encyclopaedia Britannica.
Mr. Cauz said that he believed Britannica’s competitive advantage with Wikipedia came from its prestigious sources, its carefully edited entries and the trust that was tied to the brand.
“We have very different value propositions,” Mr. Cauz said. “Britannica is going to be smaller. We cannot deal with every single cartoon character, we cannot deal with every love life of every celebrity. But we need to have an alternative where facts really matter. Britannica won’t be able to be as large, but it will always be factually correct.”
But one widely publicized study, published in 2005 by Nature, called into question Britannica’s presumed accuracy advantage over Wikipedia. The study said that out of 42 competing entries, Wikipedia made an average of four errors in each article, and Britannica three. Britannica responded with a lengthy rebuttal saying the study was error-laden and “completely without merit.”
The Britannica, the oldest continuously published encyclopedia in the English language, has become a luxury item with a $1,395 price tag. It is frequently bought by embassies, libraries and research institutions, and by well-educated, upscale consumers who felt an attachment to the set of bound volumes. Only 8,000 sets of the 2010 edition have been sold, and the remaining 4,000 have been stored in a warehouse until they are bought.
The 2010 edition had more than 4,000 contributors, including Arnold Palmer (who wrote the entry on the Masters tournament) and Panthea Reid, professor emeritus at Louisiana State University and author of the biography “Art and Affection: A Life of Virginia Woolf” (who wrote about Virginia Woolf).
Sales of the Britannica peaked in 1990, when 120,000 sets were sold in the United States. But now print encyclopedias account for less than 1 percent of the Britannica’s revenue. About 85 percent of revenue comes from selling curriculum products in subjects like math, science and the English language; 15 percent comes from subscriptions to the Web site, the company said.
About half a million households pay a $70 annual fee for the online subscription, which includes access to the full database of articles, videos, original documents and to the company’s mobile applications. At least one other general-interest encyclopedia in the United States, the World Book, is still printing a 22-volume yearly edition, said Jennifer Parello, a spokeswoman for World Book Inc. She declined to provide sales figures but said the encyclopedia was bought primarily by schools and libraries.
Gary Marchionini, the dean of the School of Information and Library Science at the University of North Carolina at Chapel Hill, said the fading of print encyclopedias was “an inexorable trend that will continue.”
“There’s more comprehensive material available on the Web,” Mr. Marchionini said. “The thing that you get from an encyclopedia is one of the best scholars in the world writing a description of that phenomenon or that object, but you’re still getting just one point of view. Anything worth discussing in life is worth getting more than one point of view.”
Many librarians say that while they have rapidly shifted money and resources to digital materials, print still has a place. Academic libraries tend to keep many sets of specialized encyclopedias on their shelves, like volumes on Judaica, folklore, music or philosophy, or encyclopedias that are written in foreign languages and unavailable online.
At the Portland Public Library in Maine, there are still many encyclopedias that the library orders on a regular basis, sometimes every year, said Sonya Durney, a reference librarian. General-interest encyclopedias are often used by students whose teachers require them to occasionally cite print sources, just to practice using print.
“They’re used by anyone who’s learning, anyone who’s new to the country, older patrons, people who aren’t comfortable online,” Ms. Durney said. “There’s a whole demographic of people who are more comfortable with print.”
But many people are discovering that the books have outlived their usefulness. Used editions of encyclopedias are widely available on Craigslist and eBay: more than 1,400 listings for Britannica products were posted on eBay this week.
Charles Fuller, a geography professor who lives in the Chicago suburbs, put his 1992 edition on sale on Craigslist last Sunday. For years, he has neglected the print encyclopedias, he said in an interview, and now prefers to use his iPhone to look up facts quickly. He and his wife are downsizing and relocating to California, he said, and the Encyclopaedia Britannica will not be coming with them, a loss he acknowledges with a hint of wistfulness.
“They’re not obsolete,” Mr. Fuller said. “When I’m doing serious research, I still use the print books. And they look really beautiful on the bookshelves.”
