This paper investigates the academization of library and information science (LIS)educators in Australia from 1959 to 2008. Extensive data document the distribution of these academics in Australian higher education institutions over fifty years: from a slow beginning in the 1960s, to rapid growth in the 1970s, relative stability in the 1980s, and a persistent decline from the 1990s. Results of other characteristics of Australian LIS educators over the fifty-year period are presented including: previous positions held before entering academia, what and where academic qualifications were obtained, academic positions/ranks by gender, mobility within Australian higher education institutions, and years spent as Australian LIS educators. Although there has been a steady decline in the number of Australian LIS educators since the 1990s, the level of academic qualifications and percentage with doctorates have risen, thus conforming to a major requirement of academia; however, the relative decline in junior academic positions is a worrying trend. The analysis of changed characteristics over time helps define who Australian LIS academics are, and additionally provides data that contributes to LIS academic workforce planning.
