Title: Publication Trends in Astronomy: The Lone Author Authors: Edwin A. Henneken
In this short communication I highlight how the number of collaborators on papers in the main astronomy journals has evolved over time. We see a trend of moving away from single-author papers. This communication is based on data in the holdings of the SAO/NASA Astrophysics Data System (ADS). The ADS is funded by NASA Grant NNX09AB39G.
