INSPEC adds IPC codes and author's email addresses

01. February 2010

As of January 2010 INSPEC (Information Service for Physics, Electronics and Computing), produced by The Institution of Engineering and Technology (IET), is mapping its own indexing schemes to the WIPO IPC scheme to assign IPC codes to relevant records. Initial trials indicate that about 75% of Inspec records will contain IPC codes, and that the average record with these codes will have two assigned to it. The IPC scheme and Inspec do not cover exactly the same conceptual territory or approach. Consequently the level of precision of the IPC codes applied varies depending on the relationships between the schemes and specific subjects themselves.

On STN the implementation of the IPC codes is available since February 1, 2010.

The IPC codes are indexed and displayed in the new search field /IPC. An online thesaurus has also been installed.
Additionally the combined code and text is indexed and displayed as bound phrase in the classification code (/CC) field. Single terms from the IPC text are also searchable.
The backfile to 1969 (but not the archive) will be loaded later this year.
For more information about IPC codes which occur in Inspec records see

A further enhancement of INSPEC: Author's email addresses are searchable in /EML and /CS and displayed in field AU. EML is custom display only.
