There were about 100 contributors to Rees's Cyclopædia, most of whom were Nonconformists. They were specialists in their fields, covering science, technology, medicine, manufacturing, agriculture, banking and transportation, as well as the arts and humanities. A number were members of the teaching staffs of the Royal Military Academy, and the Addiscombe Military Seminary of the East India Company. Other contributors were working journalists who wrote for scientific, medical and technical periodicals of the time. Several of the contributors were active in radical politics; one was gaoled for sedition and another indicted for treason.
Amongst the eminent writers engaged by Rees were Dr Charles Burney (1726–1814) who wrote on music and musical biography; Dr Lant Carpenter (1780–1870) on education, mental and moral philosophy; Tiberius Cavallo (1799–1809) on electricity and magnetism; John Farey, sr. (1766–1826), on canals, geology, music and surveying; John Farey, jr. (1791–1851) on machinery, manufactures, steam engine, and water. He also contributed a great number of the illustrations; John Flaxman (1755–1826) on sculpture; Luke Howard (1772–1867) on meteorology; John Landseer (1769–1852) on engraving; Sir William Lawrence, (1783–1867) on human and comparative anatomy; Sir James Edward Smith (1759–1828) on botany; David Mushet on metallurgy and chemistry; Rev. William Pearson (1767–1847) on astronomy; Sir Thomas Phillips (1770–1875) on painting.
Among the artists and engravers employed were Aaron Arrowsmith (1750–1823) who engraved the maps; William Blake (1757–1827) who made engravings to illustrate some of the sculpture articles; Thomas Milton (1743–1827) who engraved most of the natural history plates; Wilson Lowry (1762–1824) who engraved numerous of the plates especially those relating to architecture, machinery and scientific instruments.
With the exception of the botanical articles by Sir James Edward Smith, none of the articles are signed. Names were recorded in the Prospectus of 1802, the introduction at the start of the first volume, the paper covers of the unbound parts which have survived, and in a paper in the Philosophical Magazine, published in 1820. The following alphabetical list has been compiled from the foregoing sources. The majority appear in the Dictionary of National Biography, and in sources listed in the British Biographical Index, but these accounts rarely record an involvement with the Cyclopædia.

List of contributors by topic The previous list has been sorted into subject areas. It allows contributors of many single articles, usually of monograph length, to be identified. However a number of subjects, such as architecture and chemistry, have multiple contributors, so individual attributions are not possible.
