The New York Times and the Wall Street Journal often change article headline wording between online version and the versions found here. Search on keywords, if full titles don't work.
Also, we do not have access to the nice web interfaces that you get at nytimes.com, wsj.com, and others. (Those are very expensive.) But we do have all or almost all the text content.
We also get these newspapers (NYTimes, WallSJ, WaPo) through Nexis Uni, but these links into ProQuest give you list of last day's story, starting with page 1A. See this list of News Databases.
