We present Very Large Telescope VIMOS, Keck DEIMOS and Keck LRIS multi-object spectra of 367 sources in the field of the z~3.09 protocluster SSA22. Sources are spectroscopically classified via template matching, allowing new identifications for 206 extragalactic sources, including 36 z>2 Lyman-break galaxies (LBGs) and Lyman alpha emitters (LAEs), eight protocluster members, and 94 X-ray sources from the ~400ks Chandra deep survey of SSA22. Additionally, in the area covered by our study, we have increased by ~4, 13, and 6 times the number of reliable redshifts of sources at 1.0<z<2.0, at z>3.4, and with X-ray emission, respectively. We compare our results with past spectroscopic surveys of SSA22 to investigate the completeness of the LBGs and the X-ray properties of the new spectroscopically classified sources in the SSA22 field.
