Dear Colleagues, The American Linear Collider Workshop will take place July 13-16 at Cornell University in Ithaca, NY. The purpose of this workshop is to bring together the community of physicists in North America who are engaged in or curious about the international high-energy electron-positron Linear Collider. This workshop is one of a semi-annual series sponsored by the American Linear Collider Physics Group (ALCPG) (http://blueox.uoregon.edu/~lc/alcpg), and follows on workshops held at the University of Texas at Arlington and the University of California at Santa Cruz. The Cornell workshop will include sessions on the physics of the Linear Collider, on the detector, and on accelerator research. It differs from past workshops in that it will include an expanded accelerator physics component. A limited number of travel grants are available for students, post-docs and junior faculty. We invite you to attend this workshop. More information is available at http://www.lns.cornell.edu/public/LC/workshop/. Ritchie Patterson, for the Organizing Committee
