Everyone, We are doing an upgrade to our card reader system. When we start the upgrade, ALL doors to Birck will lock for about 15 minutes. We will try and man the doors as they lock to let people in. Please call me if you have any problems 496-1173 or 494-4491. Thank you, Mary Jo Totten Birck Nanotechnology Center Discovery Park/Purdue University 1205 West State Street West Lafayette, IN 47907-2057 (765) 496-1173 Your imagination is your preview of life's coming attractions" -Albert Einstein
