The third yearbook of the Astronomische Gesellschaft (AG) contains 19 contributions dedicated to the topic "Accretion and Winds". Modern developments in accretion-disk theory are presented; accretion disks are considered in close binaries, cataclysmic variables, neutron stars, and galaxies. Stellar winds are discussed in the context of hot, late-type, Wolf-Rayet, supergiant, young, and variable stars. In addition, the book contains review and highlight papers in the fields of helioseismology, the interstellar medium, and supernova remnants and a personal perspective before launch of the Hubble Space Telescope.
