Abstract
Galactic cosmic rays represent a directly accessible sample of
matter that originates outside the solar system. The element and
isotope distribution of this high-energy material is a record that was
molded in the fires of nucleosynthesis in other regions of the galaxy,
and imprinted by subsequent nuclear and electromagnetic processes that
have altered its composition. Recently, significant new advances have
been achieved in reading this record, brought about in large part by
the launch of new high-resolution instrumentation for measuring the
charge, mass, and energy distribution of cosmic ray nuclides. In
general, the data from these new experiments are telling us what is
different about this extra-solar sample.

It is a pleasure to acknowledge informative discussions
of the data with many experimenters, including P.H. Fowler, M. Israel and L. Koch, who contributed unpublished results from their
experiments. I appreciate the use of unpublished calculations provided
by S. Margolis, J.F. Ormes, R.J. Protheroe, R. Silberberg, C.J. Waddington, and M.E . Wiedenbeck. E.C. Stone made a number of helpful
suggestions that improved the written version of this paper. Finally,
I thank the Centre National d'Etudes Spatiales and the Centre National de
lE._ Recherche Scientifigue for helping to support my stay in Paris. This
