Hurricane Katrina news research progress

So far i have used an internet search engine to find several useful articles (including one from San Fransico Chronical), and some statistical data of TV audiences in America during the hurricane Katrina crisis from Nielsen Media Research. I have also found some textual news footage from NBC and Fox news, and am planning to send an e-mail a questionnaire to a professor of sociology at San Diego University who has done relevant research into my topic. I next plan to do check for any relevant books that may be useful, and perform a focus group that has seen the news broadcasts.
