I have had an occasional issue with the New York Times recipe including some articles in the Kindle's "Section's & Articles" index page but selecting the article there brings up the following article. So, the article is in the index page but the article content appears not to have been captured.
This happened today with the article "
Traveling Through Venezuela,
a Country Teetering on the Brink." The article is listed in
today's paper and was in the index but not in the download. I'd strongly wager it has something to do with the article being a feature that has a big photo at the top -- the content scraper probably has issues with that big photo.
