Alternative Editions
In 1961, World Book produced a Braille edition, which filled 145 volumes and nearly 40,000 pages. The project was mainly an effort in goodwill, for the company did not see its way clear to selling enough copies of the set to cover production costs. Eventually, all sets of the Braille edition were donated to several institutions for the blind. In 1964, the company also published a large-print edition.
An electronic version of the encyclopedia for Macintosh and Windows computers first appeared in 1990, but didn't have as much impact as the only other CD-ROM encyclopedia available at that time, Academic American Encyclopedia.
An international version, aimed at English-speakers outside of North America, was also produced in 1992.
Since 1998, in addition to the print and CD-ROM editions of the 22-volume, 13,800-page encyclopedia, World Book also publishes an online version called the World Book Online Reference Center. The online version includes all of the articles contained in the print set as well as several thousand additional articles and the contents of every yearbook World Book has published since 1922.

Famous quotes containing the words alternative and/or editions:
“If you have abandoned one faith, do not abandon all faith. There is always an alternative to the faith we lose. Or is it the same faith under another mask?”
—Graham Greene (1904–1991)
“The next Augustan age will dawn on the other side of the Atlantic. There will, perhaps, be a Thucydides at Boston, a Xenophon at New York, and, in time, a Virgil at Mexico, and a Newton at Peru. At last, some curious traveller from Lima will visit England and give a description of the ruins of St Paul’s, like the editions of Balbec and Palmyra.”
—Horace Walpole (1717–1797)
