I have anonymized the paper drafts and correspondence as much as
feasible.

For the paper drafts, I only included the first part of each draft --
the part that dealt with the framing of the problem and the
theoretical treatment.  I left off the data analysis example, and the
references (already there are too many pages for you to read!).

For the earlier rounds, I no longer have the cover letters that
accompanied the ms.  But those cover letters are very simple:

--------------------------------------------------------------

Dear XXX,

publication in YYY.  The authors are A, B, and C, and I am the
corresponding author.

We look forward to hearing from you.

sincerely yours,

XXX

NOTE: If the ms is a revision, I would suggest replacing "our ms" with
"our revised ms", and I would add a sentence saying something like

  We have also attached a list of the referees' comments, along with a
  description of how we handled each commment in the revision.

That's it!
