It's easy to find list of Biblical manuscripts from the 2nd to 5th centuries.

Are you aware of any lists of datasets of early manuscripts of non-canonical Christian texts?

e.g. works of Irenaeus, Justin Martyr, 1 Clem, Didache, Shepherd of Hermas, Muratorian Canon, Apocalypse of Peter, Unknown Gospel etc, all the bits and bobs of Christian writings that are not part of anyone's Bible in the modern era.
