Thanks for sharing this info with us!
What they are doing makes sense in a financial way and it is a push to get more of the literature distributed to the public.
It will be interesting to see what the revisions are in the books, also as mentioned in the letter, they will be using quotations from the revised NWT in them.
They know now how much literature was produced during the just ended 2014 SY, thus saw an increase and want to get the number requested reduced if possible, while not restricting what publishers want or need for themselves or their fs.
They have had articles in the past in the km about publishers making good use of publications and not wasting any and that congs should reduce the amount of mags requested if there is a large surplus of left over copies.
