Following a short evolutionary history of the HENSA Unix service, we
look in some detail at three of the newer facilities being offered, the
World Wide Web proxy cache, indexing of the archive, and the
bibliographic service. We describe briefly the current contents of the
software repository which has, by user demand, been extended to mirror
more sites. Finally we present some usage statistics and comment on the
way in which access to HENSA Unix has changed recently.
