The New International Encyclopedia was an American encyclopedia first published in 1902 by Dodd, Mead & Co.. It descended from the International Cyclopaedia (1884) and was updated in 1906, 1914 and 1926.

Chambers's Encyclopaedia was founded in 1859 by William and Robert Chambers of Edinburgh and became one of the most important English language encyclopaedias of the 19th and 20th centuries, developing a reputation for accuracy and scholarliness that was reflected in other works produced by the Chambers publishing company. The encyclopaedia is no longer produced. A selection of illustrations and woodblocks used to produce the first two editions of the encyclopaedia can be seen on a digital resource hosted on the National Museums Scotland website.
