Query: Towards an understanding of nucleon spin structure: from hard to soft
  scales   The workshop "The Helicity Structure of the Nucleon" (BNL June 5, 2006) was
organized as part of the 2006 RHIC & AGS Users' Meeting to review the status of
the spin problem and future directions. The presentations can be found at

Recent data suggests small polarized glue and strangeness in the proton. Here
we present a personal summary of the main results and presentations. What is
new and exciting in the data, and what might this tell us about the structure
of the proton ?
