How Big is the Holy Writ?

Something has been bugging me for some time, just how big is the writ? Considering what the Writ supposedly contains I'd think it was monstrous but there are copies that fit in a cassock pocket.

Now, from what I understand the Writ contains ten books:

Langhorne - Law
Bedard - Mental Health
Pasquale - Physical Health
Sondheim - Farming
Truscott - Animal Husbandry
Schueler - Defines heresy and punishment
Jue-Jing - Technology limitations
Chihiro - History
Andropov - Fortune, luck?
Hastings - Geography

Each of these books is implied to be a textbook of what is and isn't allowed packaged in the presentation of a religious rite. (Pasquale being a prime example, if you don't follow the disinfectant ritual infection will likely occur.)

Now here is where I start scratching my head. Typically, a textbook teaches theory about how and why something occurs and how to apply it under different circumstances. (Example being a geology textbook and how different terrain features are most likely to contain particular mineral deposits.) Theory encourages asking questions and finding ways to apply the knowledge in a practical manner.

The 'Archangels' though, would absolutely NOT want to teach theory. In order to maintain the technology level experimentation would be a very BAD thing, that's why they used religious rites and explanations to prevent those pesky "Why?" questions. It is severely implied the Writ uses a form of 'In circumstance A do procedure B and nothing else'. However, that would require explanations for an inconceivable number of situations, you'd need a dragon to haul your copy of the Writ around.

Now, in Schism Rent Asunder, when Paityr accepts the position of head of the patent office and is being shown his new office, it is mentioned the room contains floor to ceiling bookcases holding all the required reference materials including the Writ, Commentaries, Insights and Testimonies.

So perhaps these 'reference materials' contain the details of the various rites as dictated by the 'Archangels' for practical use and the Writ is just a collection of generalities through the lens of religious format (Thee's and Thou's and so forth).

However, the way the Writ is presented implies that EVERYTHING is included in it which brings me back to the question, just how big is it anyway?

The first point, is that everything is as RFC says (all hail).
However consider how some Bibles are printed in small fonts on almost tissue paper, and can fit in a pocket.
Meanwhile Grand Bibles require a strong person to lift them, and there are whole libraries ful of theological works, analysing the topics.

I think this came up once before on the forums, and if memory serves the answer was that the pocket-sized Writs are Langhorne, Bedard, and Chihiro -- the sort of books one could preach from on a Wednesday.
