SALES BACK UP: Since Encyclopaedia Britannica announced plans to end its print editions, sales have skyrocketed.
THE NUMBERS: It has sold all but 800 of the 4,000 sets of the 32-volume 2010 edition it had left at a Kentucky warehouse. The company says it will likely sell out by the end of the month.
KEEPING A FEW: The company plans to hold onto a few sets so they can be displayed somehow or donated to museums.
