First the NY Times corrected their pre-written obit of WFB to reflect books that were already published. 

Then the Times corrected the number of books Mr. Buckley had written.

And I just checked back to re-read the obit only to find a third correction:

An earlier version of this article included an outdated reference to books Mr. Buckley published in 2007 and to the total number of books he wrote, and referred incorrectly to his father, who was not a junior.

UPDATE (Thursday) It looks like yesterday’s three versions of the obituary were just rough drafts.  A brand new version is up today, with no mention of yesterday’s corrections.
