The SPIN@FERMI collaboration has updated its 1991-95 Reports on the acceleration of polarized protons in Fermilabs Main Injector, which was commissioned by Fermilab. This Updated Report summarizes some updated Physics Goals for a 120-150 GeV/c polari
zed proton beam. It also contains an updated discussion of the Modifications and Hardware needed for a polarized beam in the Main Injector, along with an updated Schedule and Budget.
