Astronomical Almanac to Be Revised
The publishers of the Astronomical Almanac are seeking reader input into possible format and content revisions. Proposed changes for the annual volume, a joint publication of the Astronomical Applications Department of the U.S. Naval Observatory and the H. M. Nautical Almanac Office of the Royal Greenwich Observatory, include adoption of the International Celestial Reference Systems and the addition of a companion CD-ROM. The changes are expected to be incorporated into the 2002 edition of the almanac.

Almanac users wanting to voice their opinions on possible revisions can complete a survey available on the World Wide Web at http://www.ast.cam.ac.uk/nao/survey.html. The survey site will close on August 1, 1998.

NASA History Takes Leopold Prize
The Organization of American Historians recently awarded the 1998 Richard W. Leopold Prize to Andrew J. Butrica's To See the Unseen: A History of Planetary Astronomy.
