(4 LINEAR COLLIDER RESEARCH AT SLAC*

We, at SLAC, are in the process of preparing the SLC, the first linear collider, for the initial physics run in the spring of 1988. The present status of that process is covered in Ref. 1 and 2, and also in Ref. 3 which appears in these proceedings. Therefore, the time is ripe for initial investigation into the next generation of linear colliders
