A global paleointensity database constructed from all published data based on volcanic rocks in geological time older than 0.03 Ma is now available and ready for use. It can be obtained from the authors as text files on a 3.5″ diskette in MS-DOS or Macintosh format or via e-mail. It includes not only major parameters, but also minor details that can be used to assess data quality. Each datum consists of reference, latitude and longitude of the site, age and its error, experimental method, site identification, site mean paleointensity and its error, number of samples, virtual dipole moment (VDM), polarity, inclination, and declination. The database contains a total of 1123 flow mean data retrieved from 83 original papers, which were published before or during 1991.
