In the framework of our project, we plan to publish in 2023 an edited volume that will provide an overview of the New Kingdom hieratic material stored in collections worldwide (historical and quantitative aspect), with a series of case-studies discussing unpublished documents from museums and institutions (qualitative aspect). We envision one historico-quantitative paper and some case-studies per institution, depending on the size of the collection and the number of involved in its publication. The volume will be published in the Aegyptiaca Leodiensia (Presses Universitaires de Liège) series; the call for papers has been sent out recently.
