We report a measurement of the reaction K+K in both tagged and untagged events at PEP. The cross section rises with invariant mass to about 15 nb at 2 GeV and falls slowly at higher masses. We find clear evidence for the processes and K*0(892)K. Upper limits (95% C.L.) of 1.5 and 5.7 nb in the mass range from 1.7 to 3.7 GeV are obtained for 0 and K*0K*0 production, respectively.
