In 2010 Langlands wrote an article with the title [*Funktorialität in der Theorie der automorphen Formen:  Ihre Entdeckung und ihre Ziele*][1].  On the IAS website, he says that 

>This note ... was written as commentary to accompany the original letter in a collection of documents on reciprocity laws and algebraic number theory, ... to appear.

By the *orginal letter* he means of course his famous [Letter to André Weil][2] in which the Langlands conjectures were first formulated.

**Questions.** Has this collection of documents already appeared ?  If not, when and where is it likely to appear ?  What other documents does it contain ?
