DESCRIPTION:Just like atomic and nuclear systems\, the nucleon has an exci
 tation spectrum which is a consequence of its nature as a composite system
 . This resonance spectrum is a reflection of the underlying strong interac
 tion\, namely QCD. In contrast to nuclear and atomic systems these nucleon
  resonances have large widths and can be difficult to separate experimenta
 lly. On the other hand\, QCD is nonperturbative in this energy region maki
 ng a prediction of the spectrum directly from QCD very difficult. Since nu
 cleon resonances can be excited with photons and mesons\, methods are pres
 ented to investigate such excited states through the photoproduction of pi
 ons\, etas and kaons in a coupled-channels framework. The role of polariza
 tion observables is pointed out in the search for the so-called "missing r
 esonances".Just like atomic and nuclear systems\, the nucleon has an excit
