Annual Research Reports

Choose a research report volume from 1983 to 2007. Reports subsequent to the formation of the GTI in 1987 are given Volume numbers. The actual publication date for a volume is one year after the title date (e.g. the 1994 research report - Volume 8 - was published in 1995). To access reports, choose a year and select the desired article by clicking on its title in the initial table of contents PDF. For our newest posted reports, from 2008-2012, simply use the drop down menus and select the report you would like to review or print. Check back regularly as more recent reports will be posted as soon as they are received from members of the GTI research community.
