I don't find any documentation for the data set "named texts" which leaves me unable to verify whether data is available on what I would think of as "named texts".
Sorry, we haven't yet shipped any documentation on this dataset. This data currently covers 85 canonical and deuterocanonical books of the Bible, their authors and recipients, long and short titles, and some other attributes. The intended scope includes other biblical texts with a conventional name (the Beatitudes; the Magnificat).
