...I have found an archive source that will make, MAKE an entire chapter (or at least heavily structure) a thesis chapter.

Alleluia! Alleluia! Alleluia! Alleluia! Alleluia!

Nam regnat nunc omnipotens Deus.
Alleluia! Alleluia! Alleluia! Alleluia! Alleluia!

Ipsius terra est, terra est et Christi eius, et Christi eius, qui regnat nunc et omne per aevum.

Alleluia! Alleluia! Alleluia! Alleluia! Alleluia!

Regum rex, deorum Deus! qui regnat nunc et omne per aevum.

Alleluia! Alleluia! Alleluia! Alleluia! Alleluia!

hehehhehehe...

Those magic moments...

Not meaning to put a dampner on things but ... how can you be sure that nobody else has used the same archive source for similar work to what you are doing? (I'm assuming this archive source has been available to other researchers?) Having said that, isn't it your interpretation of the materials which determines your chapter anyway?

Tell me to shut up if I'm talking nonsense.

Well the work that I want to use (a natural history from the seventeenth century) has been available for others to use. But the things I am interested in are normally in the footnotes and not what people have seen as 'valuable' before. I have not doubt that the work has been used for biographical purposes - but what I want reallty hasn't been seriously used or seen as anyhting but 'extra stuff'.
