1998 Physics and Astronomy Classification Scheme (PACS)

Changes in PACS for 1998
Note: These changes have already been included in the complete 1998 PACS available for browsing or downloading below.

The Physics and Astronomy Classification Scheme (PACS) is prepared by the American Institute of Physics (AIP) in collaboration with certain other members of the International Council on Scientific and Technical Information (ICSTI) having an interest in physics and astronomy classification. The most recent internationally agreed scheme was published by ICSTI in 1991. Revised editions of PACS are published annually, or as necessary, by AIP.

Elsevier Science adopts this scheme for its Physics and Materials Science publications with the kind permission of AIP. Comments and questions concerning the Scheme may be sent by e-mail to shameed@aip.org.
