Abstract
The heavy quark effective field theory Lagrangian is renormalized to order 1/m^2. Our technique eliminates operators that vanish by the equation of motion by continuously redefining the heavy quark fields during renormalization. It is consequently only necessary to calculate the running of the operators that do not vanish by the equation of motion. Our results are found to be consistent with reparameterization invariance.

28 pages, Latex, 7 figures, uses espfig.sty. This is a long version of our paper, giving many details of the calculation. A somewhat shortened version (HUTP-96/A026) is being submitted for publication. Replaced version: Two additional references added and discussed
