”Not merely within Sweden did Linnaeus pursue a wealth of correspondence with all Inquiring Parties, but also with many foreigners, and in particular with the most learned and Inquiring in Europe […] whereby not only was he promptly notified of what new discoveries were made in Europe, but also given access to them, so that most of the Books published were made over to him gratis […] This valuable collection of Letters would be worthy to be made public, containing many hundreds of letters, in which is discussed everything remarkable that has arisen from 1735 until his death."
(From Vita Caroli Linnaei, III)

Internet publication of
Linnaeus’ correspondence

In preparation for the 300th anniversary of the birth of Linnaeus in 2007, a project was started to publish Linnaeus’ correspondence on the Internet.

Carl Linnaeus was well aware of the scientific value of his correspondence. By the time of his death in 1778 he had received more than 3,000 letters from Europe, America, Asia and Africa. They came from natural history scientists like himself, as well as from the disciples who upon his recommendation had been sent on expeditions all over the world. In all, Linnaeus had more than 600 correspondents! Together with the 2,000 letters from Linnaeus himself that are preserved, this material represents an invaluable source for all those studying natural history research and scientific culture in the 18th century.

Available to all
For the 200th anniversary of the birth of Linnaeus 1907, publication began of the letters to and from Linnaeus. After the 10th volume, however, the project was halted by lack of funds. For the 300th anniversary, the publication project was restarted – now on the Internet. linnaeus.c18.net

The digital publication of Linnaeus’ correspondence is intended to show the letters in a variety of formats. All the letters that are preserved as original manuscripts will be published as digital facsimiles. It will therefore be possible to see the original appearance of each letter. Each letter is accompanied by a detailed summary in English, with links to biographical and bibliographical databases. The summaries and all related texts are in English because more than 90 per cent of the letters are written either in Latin or in Swedish. By documenting the content of the letters in English, we can reach a large readership worldwide.

In addition to this there are a large number of older editions and translations of Linnaeus’ correspondence available in pdf format on the website. The website also features a register of the letters, enabling searching for the correspondence between Linnaeus and the person in question.
In a later phase we intend to transcribe all the letters.

Publication of the letters is funded by the Swedish central bank through Riksbankens Jubileumsfond. Main responsibility for the project is with the Swedish Linnaeus Society, and publication of Linnaeus’ letters is also supported by the Royal Swedish Academy of Sciences, Uppsala University and Uppsala University Library, as well as The Linnean Society of London.
