The NASA Astrophysics Data System (ADS) is the primary Digital Library portal for researchers in Astronomy and Astrophysics. It is also used extensively by the broader community of Space Science Researchers. In addition to the scientific literature, the ADS has for a long time included in its database non-traditional scholarly resources such as research proposals, software packages, and high-level data products, making them discoverable and easily citable. Over the next three years, in response to NASA’s efforts supporting interdisciplinary research across Science Mission Directorate Divisions, the ADS will expand its coverage of Planetary Science and Heliophysics content. During this time, an in-depth analysis of this disciplinary content will provide us with opportunities to improve our coverage of the literature as well as linked research objects such as datasets and software, improving their discoverability and citability. In this presentation I provide an overview of the ADS system, its distinguishing features, and then focus on our efforts to support and promote the goals of Open Science.
