The online database contains around 14500 entries which summarise the contents of all the known surviving letters written both by and to Charles Darwin. Around 5000 of those entries include complete transcriptions of the letters, taken from the published volumes of The correspondence of Charles Darwin (Burkhardt et al., Cambridge University Press 1985-). Today, Darwin's letters are in more than 200 archives and private collections in at least 20 countries around the world. Look under "provenance" in the metadata to each entry to find out where the original letter, or other source of our information, is to be found. Also included in the database are short biographies of nearly 2000 correspondents and more than 1000 other people mentioned in the letters. The biographical entries of Darwin's correspondents link to complete lists of all letters he exchanged with them. There is a bibliography of printed sources which is being fully linked to references in the Database entries. This is work in progress. In cases where you cannot identify a source referred to in a footnote to a letter, please consult the print edition of the Correspondence. ... [Information of the supplier]
