This is not currently part of the peer-reviewed material of the project. Do not cite as a research publication.
As printed in ONP Registre // Indices 1989, three indexes/databases are available, but now in updated form.
It is hoped at some point that it will be possible to make these databases open to the general public for random searching.
The Bibliography gives access to all ONP's short titles. The index of Sigla, alphabetised by worktitle, explains in full detail the source of each citation. This is linked to the index of Medieval Manuscripts arranged by collection/library.
