AB  - We describe searches for B meson decays to the charmless vector-vector final states omega omega and omega phi with 471 x 10(6) B (B) over bar pairs produced in e(+)e(-) annihilation at root s = 10.58 GeV using the BABAR detector at the PEP-II collider at the SLAC National Accelerator Laboratory. We measure the branching fraction B(B-0 -> omega omega) = (1.2 +/- 0.3(-0.2)(+0.3)) x 10(-6), where the first uncertainty is statistical and the second is systematic, corresponding to a significance of 4.4 standard deviations. We also determine the upper limit B(B-0 -> omega phi) < 0.7 x 10(-6) at 90% confidence level. These measurements provide the first evidence for the decay B-0 -> omega omega, and an improvement of the upper limit for the decay B-0 -> omega phi.
