The first cooling conference was probably held in 1986, but I can find no references to it in other IDEA publications. There were apparently no proceedings published for the first three conferences in 1986, 1987, and 1988.
Contents for each individual issue are listed. Some back issues are available for purchase from IDEA. Specific articles can be obtained through larger libraries, or by contacting IDEA or Morris A. Pierce1996 - 11th Annual Conference
