Physics and Astronomy Classification Scheme

Template:Short description The Physics and Astronomy Classification Scheme (PACS) is a scheme developed in 1970<ref name = pacs-home>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> by the American Institute of Physics (AIP) for classifying scientific literature using a hierarchical set of codes.<ref name=what-is-pacs>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> PACS has been used by over 160 international journals,<ref name = pacs-home/> including the Physical Review series since 1975. Since 2016, American Physical Society introduced the PhySH (Physics Subject Headings) system instead of PACS.

Template:AnchorDiscontinuation

AIP has announced that PACS 2010 will be the final version, but it will continue to be available through their website.<ref name = pacs-home /> The decision was made to discontinue PACS, owing to the administrative complexity of the revision process and its future viability in light of changing technological and research trends. However, PACS is still in use by scientific journals.<ref>PACS cloud. Reports on Progress in Physics. 2013. (scroll to the bottom of the page)</ref>

In association with Access Innovations, Inc., the AIP has developed a new "AIP Thesaurus",<ref name=AIP-thesaurus-press-release>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> which it states will enable faster, more accurate and more efficient searches.
