Various experimental techniques for point contact production are described. ;Examples of point-contact spectra are presented for pure metals, alloys and compounds, as well as for semimetals and semiconductors, heavy fermion systems, Kond-lattices, mixed valence compounds and more. Superconducting point contacts are considered in respect to Andreev reflection and Josephson effects. Special attention is paid to contact conductance fluctuation, and new trends of research are outlined. INDICE: Introduction.- Metallic point contacts as a physical tool.- Fundamentals of PCS theory.- Experimental techniques.- PCS of quasiparticle excitations.- PCS of non-photonic scattering mechanisms.- Thermal effects in point contacts.- Point contacts in magnetic fields.- Electrical fluctuations in point contacts.- Point contacts under irradiation.- PCS of semimetals, semiconductorsand dielectrics.- PCS of superconductors.- PCS of high-Tc and other uncommon superconductors.- PCS of heavy-fermion systems.- New research trends.
