Indexing and Abstracting
The Conference Publication Program (CPP) assures wide distribution of conference proceedings by providing abstracting and indexing of all individual conference papers for inclusion in worldwide databases. The CPP makes every reasonable attempt to ensure that abstracts and index entries of content accepted into the program are included in databases provided by independent abstracting and indexing (A&I) services. Each A&I partner makes its own editorial decision on what content it will index. IEEE cannot guarantee entries are included in any particular database.
The IEEE provides SCOPUS with all of the IEEE Xplore digital library content so that the bibliographic information (what is seen on an abstract page in IEEE Xplore, including the abstract) can be made visible. While we do provide them with all of our content, it is not our policy to determine what Scopus will or will not index. Additionally, once SCOPUS does load IEEE records, and the abstract is viewable to their users, the user can then link back to IEEE Xplore and lands on the abstract page of that particular record, enabling you to either view through a subscription or purchase the full text article.

GOOGLE and other Indexing services
IEEE content is indexed by Google. Additionally, IEEE has agreements in place with other publishers and services to include IEEE papers in their online and print indexes. Examples include INSPEC, Thomson Reuters’ Web of Science, Ei Engineering Village and Scitopia.org.
