One problem I never resolved is 
which supposedly created 10 new départements. The document was very sparse, 
and gave no details, other than which département was being split to create 
the new one. Because this post-dates the maplibrary.org dataset (2007) by 
their admission, I suppose it could be considered accurate as of that date, 
but this is something that should be resolved at some point.

Someone in tune with legal issues should look at their source list - I 
wasn't completely sure it was all PD.

I'm not sure there can be such a thing. If there is an existing border, 
even if it's not edited, who's to say which one is right? Now, it could be 
(and has been) interesting work researching discrepancies, but it's a big 
job most of the time.

NE2 and I spent a while just to research a very small section of the US/MX 
border (~ 25.934, -97.569), coming to the conclusion that some official 
datasets, including UN's SALB, were wrong. Unlike those sources that have a 
straight latitudinal line through the area, Maplibrary.org does show the 
correct shape of the border - following the river - but is offset ~150m 
north. I don't know if that is within the expected accuracy for that 
dataset or not (
