 Summary Sheet


Producer: The Institution of Engineering and Technology (IET), UK in association with FIZ Karlsruhe, Germany
Coverage:1979 - 1994
File Size: 613.260 records
Updates:  Closed file
File Type:Bibliographic
ContentPhysics, astronomy, astrophysics

The INSPEC PHYS Supplement Backfile (INSPHYS) database covers the worldwide literature on all fields of physics, astronomy, astrophysics and related areas. Special emphasis is given to non-conventional and East European literature. Citations, mostly with abstracts, are in English. In addition, non-English original titles are available. Bibliographic information, indexing terms, abstracts, and element terms are all searchable. The PHYS Thesaurus is available online in the Controlled Term (/CT) field. INSPHYS is a supplementary file to the INSPEC database and contains only those records of the former PHYS file from 1979 to 1994 which did not appear in INSPEC. To obtain complete results, it is necessary to use INSPHYS in combination with INSPEC either by multifile or crossfile searching.
