This is a nice survey article about neutrino astronomy. I have only
skimmed it (83 pages...), but it seems very readable to people outside
the field (like me).

High-energy Neutrino Astronomy: The Cosmic Ray Connection
Authors: Francis Halzen, Dan Hooper
Comments: 83 pages, 18 figures, submitted to Reports on Progress in Physics
Report-no: MADPH-02-1265
This is a review of neutrino astronomy anchored to the
observational fact that Nature accelerates protons and photons to
energies in excess of $10^{20}$ and $10^{13}$ eV, respectively.
Although the discovery of cosmic rays dates back close to a
century, we do not know how and where they are accelerated. Basic
elementary-particle physics dictates a universal upper limit on
their energy of $5\times10^{19}$ eV, the so-called
Greisen-Kuzmin-Zatsepin cutoff; however, particles in excess of
this energy have been observed by all experiments, adding one more
puzzle to the cosmic ray mystery. Mystery is fertile ground for
progress: we will review the facts as well as the speculations
about the sources including gamma ray bursts, blazars and top-down
scenarios.
The important conclusion is that, independently of the specific
blueprint of the source, it takes a kilometer-scale neutrino
observatory to detect the neutrino beam associated with the
highest energy cosmic rays and gamma rays. We also briefly review
the ongoing efforts to commission such instrumentation.
