  The techniques used to study top quarks at hadron colliders are presented.
The analyses that discovered the top quark are described, with emphasis on the
techniques used to tag b-quark jets in candidate events. The most recent
measurements of top quark properties by the CDF and DZero collaborations are
reviewed, including the top quark cross section, mass, branching fractions and
production properties.
  Future top quark studies at hadron colliders are discussed, and predictions
for event yields and uncertainties in the measurements of top quark properties
are presented.
