Abstract
Extensive searches for evidence of compositeness of quarks and leptons have
been made in
the complete set of ALEPH data from LEP running at the Z peak. These include
searches for radiative and weak decays of excited fermions, produced either in
pairs or singly, and a scalar partner of the Z. Coupling and branching ratio
limits deduced from these searches are presented.
