Our journal, book and chapter checklists help researchers assess where to publish and make informed choices. Different researchers need different formats. That’s why we’re delighted to launch an interactive journal checklist: bit.ly/47oYBLp
bit.ly
Journals • Think. Check. Submit.
The checklist is a tool that will help you discover what you need to know when assessing whether or not a publisher is suitable for your research.
