AASTeX allows authors to Patrick Daly’s natbib package to manage citations. The natbib package re-implements LaTeX’s \cite command, and offers greater flexibility for managing citations in the author-year form. A short guide is available.

AASTeX Symbol Fonts

The AASTeX package contains a collection of assorted macros for commonly-used astronomical symbols and abbreviations. Go here for more information.

Facility Keywords

To aid organizations in obtaining information on the effectiveness of their telescopes, the AAS has created a vocabulary of facility keywords for telescope facilities for use in journal articles. The use of a common set of facility keywords across astronomical publications will make searches for telescopes significantly easier and more accurate. The current list of over 600 recognized keywords is available here.
