The now digital-only service will come to Apple devices in the shape of a dedicated app that charges £1.99 per month.
Last month, Britannica announced that it would no longer be publishing 32-volume print editions after 244 years in print. The Chicago-based company was struggling to compete with online services such as Google and Wikipedia.
The subscription service grants iOS users access to all 80,000 Britannica articles, which include contributions from ex-US president Bill Clinton and Archbishop Desmond Tutu.
iPhone and iPad users can also take advantage of diagrams, charts and photographs. A LinkMap will enable them to make connections between articles.
The Encyclopaedia Britannica app for Apple devices is free to download. Users who do not wish to pay for a subscription can access a number of entries, including the Top 100 articles and the 'One This Day' feature.
