Why are many flown lunar orbit and surface checklists and maps printed on one side only? Considering the weight restrictions (and space) it seems like a lot of unnecessary cargo.

If just some of the checklist books and map books were printed on both sides it probably save a few kilos at least. Being NASA, I am assuming there is a very good explanation for this.

All of the checklist pages I have handled over the years have all been double sided. I don't recall ever seeing a single sided checklist page except those which were the start or end of a section.

A lot of the maps were single sided, but many of those seemed to be actual photographic prints which obviously only had one side which was light sensitive during the wet photographic print process.

Other maps were printed on very thin paper, which you could see through when held up to light, so the two sides would probably interfere with each other.
