The Sloan Digital Sky Survey has led to numerous new discoveries and a rich and rapidly growing body of literature. We assess the impact of SDSS on astronomy research from multiple perspectives including analyzing co-authorship, charting networks of scientific keywords, identifying emerging "hot” research topics, and mapping the sky distribution of archival data queries. We find evidence from co-authorship that the SDSS has encouraged international collaboration. Each data release triggers a new burst of hot topics, such as "dark matter” after the first data release, and "stellar metallicity” after the second data release. We find interesting patterns in the spatial distribution and time sequence of database queries for selected astronomical objects.
