The detection and identification of gamma-ray lines from the galactic center direction are reviewed; the principal line of interest is the 511 keV line from electron-positron annihilation. Attention is given to line features detected at 476 plus or minus 24 keV, at 530 plus or minus 11 keV and at higher energies. It is noted that only the 511 keV line shows a statistically significant difference between target and background count rates, with the effect being independent of the direction in which the data were taken. Strong but not conclusive evidence for a three-photon continuum is found in the data, and it is suggested that the only galactic center gamma-ray line that has been conclusively detected is the 511 keV positron annihilation line.
