Dear Colleagues, Those of you on the DPF mailing list have received messages from Chris Quigg and Paul Grannis announcing the `Circle Line Tours' series of lectures on physics at future colliders. This is a part of the Fermilab community study on future directions for the laboratory. One purpose of the Circle Line Tours lecture series is to provide background and bibliography for the Fermilab community to document what has been done in studies for future colliders. As a part of this, Chris and Paul are making a record of the discussions available on the Web. This includes the transparencies shown by the speakers and the references they have supplied. It also includes lengthy sets of written questions posed to the speakers by the `designated interrogators', and even more lengthy written answers. For those people interested in linear collider physics, this Web archive should be an especially useful resource. Please have a look at it.
