Collect parts of the documents at the Cordon

== Walkthrough ==
The location of the documents is on the video below, with timecodes in the description.
The piece on the second floor of the northern checkpoint tends to fall from the windowsill into the inaccessible room. You can still get it as shown on the video below, and remember that looking at things into your binoculars or scopes increases your reach:
Alternatively, you can wait until you get inside that room in Mystery of the islands/Cordon. You'll need to unlock Zaton in the Black Doctor's exoskeleton storyline to start it.
== Notes ==
* If you can't find some documents, you can buy them from Informant for 20000RU apiece. However, doing that would block the final achievement.
*60 documents total in this part of the quest.
