Hello,

I am confused, is this not the official, current printed version of the documentation?
https://www.amazon.co.uk/Org-Mode-9-1-Reference-Manual/dp/1680921657

I mean, as opposed to:
https://www.amazon.com/exec/obidos/ASIN/1906966087/networktheory-20 ?

However, the latter is the version that is linked on www.orgmode.org. Is it simply outdated? 

Kind regards, 
Trond
