Exclusive channels in [bar p]p annihilation at rest provide a powerful tool for studying the meson spectrum below the [bar p]p threshold. The mesons can be classified in SU(3) multiplets according to their quantum numbers. The states which do not fit into this classification are candidates for new forms of hadronic matter like glueballs, hybrids, and multi-quark states. Recent results on the search for exotic states in exclusive channels of [bar p]p annihilation at rest are discussed. No less important is the study of the annihilation mechanism. In particular, high-statistic measurements of [bar p]p annihilation at rest into two-meson final states are an excellent tool for studying quark dynamics. Examples of two-body reactions are presented. 24 refs., 9 figs., 3 tabs.
