Effective August 14, 2009, we removed TILT.  The Open Public License version will be available until May 2010 in case anyone wants to download it and host it locally, and then it will be taken down as well. 

Although TILT has been in existence for over a decade and is still widely used around the world,  the University of Texas Libraries had to make the difficult decision to take TILT down.  We have not used TILT as part of our information literacy program since 2002.  Our new campus information literacy program, developed in concert with the School of Undergraduate Studies, takes the form of integration of approved learning outcomes in a course-specific manner for each of the freshman courses offered as one component of the Signature Course program of the core curriculum.   A comprehensive, generic tutorial like TILT will not be used in the program.  Because of the resource-intensive nature of our program, we have had to make many difficult decisions about what we would and would not continue to do.  We recognized that we would not have the resources to update TILT (and haven’t had the resources to do so for years) and would no longer have the resources to field questions from students using TILT, especially given the fact that less than 4% of TILT users are from the UT-Austin campus.  TILT will still be available under Open Public License if you want to download, modify and host it locally.  See http://tilt.lib.utsystem.edu/yourtilt/ for more information about this option.
Thanks to everyone who has written to express their appreciation of TILT.  We are glad it served so many so well for so many years.
