If somebody came, exclusively, to the Times with 251,287 stolen / leaked cables, would they have published them all?
In the Netherlands news agencies are developing search tools to make it more manageable. Something like: http://cablesearch.org/
Notably Wikileaks has released only a small amount of the 251,287 cables, and while the US government refused to vet the cables from Wikileaks, they did vet them when the NYT asked them too.
According to Wikipedia, so far they have released less than 1%.
