Funktorialität in der Theorie der automorphen Formen In 2010 Langlands wrote an article with the title Funktorialität in der Theorie der automorphen Formen:  Ihre Entdeckung und ihre Ziele.  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 original letter he means of course his famous Letter to André Weil 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?
