The IAU publishes scientific results and information in all areas of astronomy. IAU Publications comprise primarily the Information Bulletin and the Proceedings of the IAU General Assemblies and other scientific meetings sponsored by the IAU. The series of IAU Symposia, IAU Colloquia, the IAU Transactions (Vol. A and B), and the Highlights of Astronomy are published by the IAU Publisher: Cambridge Universtity Press

Electronic files will be made available to the NASA ADS (and other free-access websites as determined by the IAU) 18 months after publication for free and wide distribution.

IAU members can buy these books (paper version) from the publisher at considerably reduced prices by referring to their membership (give name and address as listed in the IAU Membership Directory).  Before 2004, the publisher of Proceedings of IAU Colloquia were decided by the Scientific Organizing Committee of each meeting and were sold through the normal distribution channels for scientific books.
