This is not currently part of the peer-reviewed material of the project. Do not cite as a research publication.
There will be some cases in which editors need to cite manuscripts (or printed sources) that are not in ONP Registre, either because they are post-medieval or are printed sources. In this category also come runic texts, where an edition must be cited as the primary source, unless the inscription is unpublished. If there is a standard siglum for sources of this type, please use it, but first consult the relevant Coordinating Editor and Tarrin Wills to check suitability.
