No! I noticed that the New York Times is saying that these documents show that the death toll is around 100,000. They do no such thing. They simply report this number of deaths. This is not the same as determining that this number has been killed, since these documents didn't set out to report all deaths. There have been very few comprehensive studies on the actual death toll, but it is much higher (see http://web.mit.edu/CIS/pdf/Human_Cost_of_War.pdf).

Well, a paper by Hess, Shanks, and Hutjens called "Accelerated Calf Growing Program" says that "ad libum" means "to appetite," which I assume means you give as much of the food/drink to the cows as they are willing to consume. So perhaps the questioner means that they made new folders whenever they got hungry instead of eating? Or that they made folders until their folder-making appetite was sated?
