  Models in which gravity and/or Standard Model gauge bosons propagate in more
than three spatial dimensions have implications that can be tested at current
colliders. In this paper, we report on the results from searches for extra
dimensions at the two Tevatron experiments, CDF and D0, which utilize up to 200
pb^-1 of proton-antiproton collision data from Run II taken at 1.96 TeV CoM
energy, between spring 2002 and fall 2003.
