ATLAS3D project is a multi-wavelength survey of a complete and volume 
limited sample of morphologically selected early-type galaxies. 
260 galaxies not exhibiting spiral arms or extended dust lanes were extracted 
from a complete parent sample of 871 galaxies brighter than -21.5 mag 
(K-band) and observed from La Palma with the SAURON integral-field 
spectrograph mounted on the 4.2 William Herschel Telescope.
Additionally, the majority of sample galaxies were observed also with the 
IRAM 30m telescope, CARMA and Westerbork interferometeric arrays, as well as 
the MegCam at the Canada-France-Hawaii-Telescope.

In this talk I will briefly describe the survey and discuss the clues for 
formation and evolution of early-type galaxies based on structure, kinematics 
and dynamics of observed galaxies, as well as their stellar populations and 
properties of gas in the cold, warm and hot phases. The main conclusions are 
that nearby early-type galaxies carry imprints of various types of formations 
processes (dissipative, non-dissipative, in-situ, ex-situ, environmental 
effects), most evident at non edge-on views of the fundamental (mass) plane, 
that velocity dispersion is the best predictor of galaxy properties and that 
spirals and early-type galaxies should be considered together, as they form a 
parallel and a continuous sequence in their properties.
