The presentation will discuss the approaches to writing such reference works (based on the speaker's experience with the Update of the ICRC Commentaries to the 1949 Conventions, and the Max Planck Encyclopedia of International Procedural Law). The presentation will discuss the approaches to writing such reference works (based on the speaker’s experience with the Update of the ICRC Commentaries to the 1949 Conventions, and the Max Planck Encyclopedia of International Procedural Law). Then a reflection will follow on how we - as researchers - use these reference works. Are references to reference works allowed in an academic paper? Are they objective, are they pointing us to existing debate, or do they make us all lazy? Reference works are an everyday presence in academic work, but should we reflect more about them?
