Proceedings policy on Impact Factors and Indexation

Under current policy, Clarivate (the owners of ISI Web of Science) do not calculate Impact Factors for ANY proceedings titles. Therefore, proceedings journals are not issued with Impact Factors.

The ISI Web of Science platform itself is split into two components: SCI (the Science Citation Index) and CPCI (Conference Proceedings Citation Index). Proceedings journals appear within the CPCI. In order to access both, users need to have a full subscription to ISI Web of Science. However, those subscribing only to the SCI component will not have access to proceedings papers.

However, it is at the discretion of Clarivate as to how quickly they process and upload new content. Unfortunately, we have no control over how long it takes for each volume to be indexed. It can often take some time for papers to appear.

Where are conference proceedings abstracted?

IOP Publishing works with all major abstracting and indexing (A&I) services to facilitate the ongoing discoverability of all published content. However please be aware that each A&I service applies its own editorial policy to content supplied for indexing. While IOP Publishing will make every reasonable effort to comply with the requirements of our A&I partners, we are unable to guarantee content will be indexed in any particular database, neither are we able to guarantee indexing in a particular time frame.
