We report the first direct measurement of bb-bar rapidity
correlations in ppbar collisions at sqrt s = 1.8 TeV.  We select events with a
high transverse momentum muon accompanied by a jet, and a second jet
associated with a decay vertex displaced from the ppbar interaction vertex.
Two independent samples are obtained corresponding to events with a forward
(2.0 < |eta| < 2.6) or central (|eta| < 0.6) muon.  We measure the ratio of
forward to central bb-bar production to be 0.361 +/- 0.033(stat.)^+0.015_
-0.031(syst.), in good agreement with the next-to-leading order QCD result,
0.338^+0.014_ -0.097.
