Frequently Asked Questions

General Information

What is the PJIP?

The PJIP is a interactive database designed to help researchers navigate the world of academic publishing. By consolidating and standardising information—such as journal rankings, acceptance rates, response times, word/page limits, and open-access status—the PJIP helps researchers to make informed decisions about where to submit their work.

What makes the PJIP especially valuable is our focus on fine-grained journal classification, obtaining operational data (e.g., review lengths and revise-and-resubmit rates), and our interactive tools that allow users to search, filter, and compare journals in meaningful ways. For a deeper look at these features, visit our homepage or to see them in action vist any one of our subject pages.

How do you add (or update) a journal?
