A citation analysis of publications produced by the Department of Atmospheric Sciences faculty at Texas A&M University was conducted. This study included a detailed analysis of 5,082 cited publications by source, format, and age. TAMU Libraries holdings were then assessed using the works cited within the context of the 80/20 rule. The sources cited were primarily journals (91 percent) and books (5 percent). Eighty percent of the cited journal articles were fulfilled by just 24 journal titles, thus adhering to the 80/20 rule. The results were compared to those of previous citation studies in the sciences, with implications for collection management.
