The 20th International Symposium on Spin Physics (2012) that was held in Dubna from September 17 to 22 was attended by about 300 participants from 22 countries. Since the Rochester Conference in 1964, this was the first Dubna forum that attracted so many scientists. This Symposium is one of the largest IUPAP conferences. The previous Symposia of this series were organized in Germany, the USA, Japan, Italy, and so on around the circle. Most participants of the Dubna Symposium were from JINR, the USA, Russia, Germany, Japan, and Italy. The program of the Symposium included 6 plenary sessions, at which 32 invited talks were presented and discussed, and 9 sections with 145 presentations devoted to the spin structure of hadrons, spin effects in reactions with lepton and hadron beams, spin physics beyond the Standard Model, future experiments as well as to the technique of polarized beams and targets and application of spin phenomena in medicine and technology. Almost all these talks are presented in the Proceedings.
