In early 2019, astronomers submitted 294 “APC” — Activities, Projects, and State of the Profession Considerations — white papers to the Astro2020 Decadal Survey on Astronomy and Astrophysics organized by the National Academy of Sciences. In partnership with the American Astronomical Society, these white papers are published here as Volume 51, Number 7 of the Bulletin. Below you may find a table of all of the APC white papers, in the order of their submission. Full text is available in PDF format. Some authors opted out of BAAS publication.
The white papers are indexed in ADS, with the full listing available as this ADS Library.
