The notebook contains one message marked as important among a heap of spam:
"Set up a camp near the waste processing station and everyone who is going to be participating in this job will join you. Don't expect Black, because he and his people will be at Jupiter on a different mission. The army has suspended all flights into the Zone, so there won't be any trouble from that side. When stalkers find a way to Pripyat we'll send a guide and wait for the client's people there - they'll show us where the lab is.
Jackal."
