We prove general common fixed point theorems for occasionally weakly compatible hybrid pairs of mappings in symmetric spaces satisfying implicit relations which generalize the theorems of [1-6, 8-14, 16-33, 36, 37, 39, 41, 44, 46-49, 51, 56, 58-63, 65-74, 76-85] and we correct the errors of [6, 21, 34, 47] and [84].
