Google Scholar is a specialized search engine from Google that searches scholarly texts, professional journals, research papers, etc. Here is a search for the 1966 Florence Flood. This is a pretty interesting resource but unfortunately it seems that most of this material must be paid for to actually view in its entirety, on the sites listed by Google Scholar all you get are abstracts (mostly). Still - it is a good starting place to at least find relevant materials, titles, etc.
