Bd0-B̄d0 oscillations are observed in "self-tagged" samples of partially reconstructed B mesons decaying into a lepton and a charmed meson collected in pp̄ collisions at √s=1.8 TeV. A flavor tagging technique is employed which relies upon the correlation between the flavor of B mesons and the charge of a nearby particle. We measure the flavor oscillation frequency to be Δmd=0.471-0.068+0.078±0.034 ps-1. The tagging method is also demonstrated in exclusive samples of Bu+→J/ψK+ and Bd0→J/ψK*0(892), where similar flavor-charge correlations are observed. The tagging characteristics of the various samples are compared with each other, and with Monte Carlo simulations.
