Just wanted to remind folks that a great way to accumulate research is to use the various wikis. You just need to study up for like 10 minutes on proper etiquette and then add your links.
http://en.wikipedia.org/wiki/Wikipedia:WikiquetteThere are three to consider using that I know of:
1) Our own demopedia, but that is only open to users who are in the BETA test. Currently there is no Katrina related material there.
2) dkosopedia. Here you only have to deal with freindly kossacks:
http://www.dkosopedia.com/index.php/Hurricane_Katrina_Chronologyhttp://www.dkosopedia.com/index.php/Talk:Hurricane_Katrina_Chronologyhttp://www.dkosopedia.com/index.php/Hurricane_Katrina_Commentary3) and, of course, "the main one", wikipedia. Here you would be advised to read the article and talk comments that are there to make sure your link or reference is new, and since this one is open to the world at large you might have to deal with a lot of churn and fight it out with freepers trying to suppress your information. I would suggest if you are not a wiki regular only editing the talk page (the first link) and letting experienced editors integrate the material.
http://en.wikipedia.org/wiki/Talk:Hurricane_Katrinahttp://en.wikipedia.org/wiki/KatrinaOne way to keep from getting caught up in churn is to start new articles that link to parts of the main article. For example, instead of editing the main Katrina article, pick a proper name or place more directly related to your material, e.g. "17th Street levee" or "International Arabian Horse Association" and place the material there along with some basic background research on the subject you chose, then link the material into the main article. That way noone can take your material out because "the article is too big" or "the article needed to be reformatted" or whatever, and your content remains there -- you only have to fight to keep it linked.
So for those that want a "master list" I highly recommend learning to use this technology, which has resulted in some very thorough and useful resources in the past.
