Carl Linnaeus received around 3000 letters and there are some 2000 letters from him preserved. He had around 6000 correspondents all over the world. His letters are available as images of the original manuscripts, but there are also english summaries as well as biographical and bibliographical data. The letters are important as sources not only to information on the work and life of Carl Linnaeus, but in general also more broadly on the 18th century and history of science.
The project was funded by Riksbankens Jubileumsfond and supported by The Linnean Society of London, The Swedish Royal Academy of Sciences and Uppsala University.
The picture on the right shows the second page of letter written by Carl Linnaeus to Abraham Bäck in 1761.
