Being the go-to resource for more than two centuries, Encyclopaedia Britannica is about to stop the presses. Its 2010 edition will be its last printing.
Volumes of the encyclopedia were a fixture in American living rooms through much of the 20th century, but the realities of the digital age have sometimes made the books irrelevant. According to The New York Times, the last print version, from 2010, was 32 volumes and weighed 120 pounds. It had a price tage of $1,395. Only 8,000 set were sold.
Sales of the Britannica peaked in 1990, when 120,000 sets were sold in the United States. But today, 85 percent of the company's revenue comes from selling text books on math, science and the English language.
