We review the search for the top quark conducted by the D-Zero collaboration using data from the Fermilab pbar-p collider. Based upon a preliminary analysis of an integrated luminosity of about 13.5 pb-1, we have searched for t-tbar production and decay in the experimental channels involving a pair of dileptons (electron or muon) plus jets, or single leptons plus jets. Summed over all channels, we observe 7 events in our data, to be compared with an expectation from background processes of 3.2 +/- 1.1 events. The t-tbar ~cross-section deduced from the small excess of events is presented as a function of the top quark mass. The statistics are sufficiently limited that no clear evidence for the existence of the top quark can be obtained. We also comment upon contributions to the Parallel session devoted to the top quark at this conference.
