Web of Science CPCI is an important term for authors who want their conference papers to appear in a recognised citation index.

Many conference websites mention Web of Science or CPCI. Some say "submitted to CPCI". Others say previous proceedings were indexed. These phrases sound similar, but they do not mean the same thing.

What Is Web of Science CPCI?

CPCI stands for Conference Proceedings Citation Index. It is part of Web of Science Core Collection from Clarivate and focuses on selected conference proceedings.

For authors, CPCI matters because it can support:

• Academic visibility
• Institutional reporting
• Citation discovery
• Conference paper recognition
• Research evaluation requirements

But coverage is not automatic.

What Authors Should Check

Before submitting to a conference that mentions CPCI, check:

• Proceedings publisher
• Source title
• Previous indexed volumes
• Whether the current volume is already published
• Whether the claim says indexed, submitted or planned
• Whether the institution accepts CPCI

The word "submitted" is especially important. Submitted does not mean accepted or indexed.

Why Past Coverage Is Not a Guarantee

Previous editions can be useful evidence, but they are not a promise. A past proceedings volume may have been covered, while a future or current volume still needs to go through evaluation and processing.

That is why authors should avoid relying only on old screenshots or past conference pages.

Red Flags to Watch

Be careful with:

• Guaranteed CPCI indexing
• No clear publisher
• No proceedings title
• No previous volume information
• Vague answers from organisers
• Pressure to pay before details are clear

Good conferences usually explain their publication route in plain language.
