Using e-mail: Queries
You may already have enough information to sift through, but often a direct question to a person can be the fastest way to get a good perspective on your topic. You might want to try a direct question to a known expert in the area of your research. To discover Internet addresses for the names of people you encountered in your research whom you'd like to interview, consult one of the Internet Directories (Some Interesting Sites for Research and Directories). Of course, many individuals don't answer "cold call" queries, but a respectful, carefully phrased, and intelligent question might yield a response.
