Farey adalah seorang penulis yang produktif, dan Profesor [[Hugh Torrens]] (lihat referensi di bawah) telah menelusuri sekitar 270 makalah yang dibuat olehnya. Empat kali lipat jumlah yang ada pada ''Catalogue of Scientific Papers'' dari [[Royal Society]]. Ia menulis banyak hal mulai dari hortikultura, geologi, meteorologi, metrologi, desimalisasi mata uang, musik dan matematika sampai paham anti perang.
Farey was a prolific writer, and Professor [[Hugh Torrens]] (see references below) has traced around 270 papers by him, quadrupling the number given by the Royal Society's ''Catalogue of Scientific Papers''. He wrote on all manner of subjects, ranging from horticulture, geology, meteorology, metrology, currency decimalisation, music and mathematics to pacifism.

Farey's most famous work is ''General View of the Agriculture and Minerals of Derbyshire'' (3 volumes 1811-17) for the Board of Agriculture. In the first of these volumes (1811) he gave an able account of the upper part of the British series of strata, and a masterly exposition of the Carboniferous and other strata of Derbyshire. In this classic work, and in a paper published in the ''Philosophical Magazine'', vol. 51, 1818, p. 173, on 'Mr Smith's Geological Claims stated', he zealously called attention to the importance of the discoveries of William Smith.
==Deret bilangan Farey==
Selain dikenang oleh para ahli sejarah geologi, namanya juga banyak dikenal dengan [[deret bilangan Farey]] yang ditulisnya sebagai ketertarikan atas matematika suara (''Philosophical Magazine'', vol. 47, 1816, hal 385-6).
Farey wafat London. Kemudian istrinya menawarkan koleksi geologi Farey ke [[Museum Britania]], namun ditolak, koleksi tersebut lalu tersebar.
==Farey sequence==
As well as being remembered by historians of geology, his name is more widely known by the [[Farey sequence]] which he noted as a result of his interest in the mathematics of sound (''Philosophical Magazine'', vol. 47, 1816, pp 385-6).
Farey died in London. Subsequently his widow offered his geological collection to the [[British Museum]], which rejected it, and it was dispersed.
