The instrumentation becoming available to study in particular AGN from
the
UV to the gamma rays is unprecedented. This will allow us to study the
primary high energy emission as well as all the effects of reprocessing
of this emission.

Detailed observations of single objects will be made, including 
variability studies. It will, however, also be important to relate the
properties of single objects with the averaged properties of samples
of AGN. It will also be important to obtain statistiscal information
on the AGN population at high energies. The aim is to have ``unbiased''
samples in which the intrinsic differences between the AGN classes can
be quantified.

A well coordinated approach to the use of these instruments could 
improve on the quantity and quality of the scientific results obtained.
