Paris, [Tuesday] 11 January, 1853
My dear Mr. Proudhon,
As for bibliographical information, I believe I have a complete list of your works on the cover of your last book.
Please accept my very friendly greetings.
Attached to this letter is a printed sheet, on an official Éditions Guillaumin letterhead paper, on which we read:
The Dictionnaire de l’Économie politique, which we have undertaken, will include short biographies of the people who have written on any branch of Political Economy, and consequently we kindly ask you to provide us with:
1° The date and place of your birth;
2° A summary of the positions you have held;
3° The list of the works you have published, indicating the number of volumes, the format and the date of publication.
It is our honor to greet you with the highest consideration.
 These letters were sent massively. Another similar document has survived, an unpublished letter by William Thomas Thornton (dated 17 June 1853), in which the British economist answered Guillaumin by stating his date and place of birth, the exact term of his office in the British East India Company, and the list of his publications.
