Beginning in 1992, ADS is a research tool that improves astronomical research, and is specifically tailored to astronomical needs. The monetary benefit to astronomy that ADS contributes is equivalent to several hundred million in US dollars every year (2005).
The SAO/NASA Astrophysics Data System (ADS) usage statistics can be used to analyze global trends in astronomical research due to it being used amongst astronomers worldwide. Those statistics revealed the direct correlation between both the number of astronomers and the amount of research an astronomer carries out and the per capita gross domestic product (GDP) of the country from where the scientist is based.
