One way to do this is to carefully monitor the letters to the editor in your local paper. Make a database file of letter writers who support the religious right's agenda. Each file in your database should note why the person is listed, and where to find a copy of their letter to the editor, or other information, in your vertical files. Sometimes radical right groups announce their meetings in the newspaper. On the other hand, you can often find out about these meetings by visiting local Christian bookstores.
Many Christian bookstores have bulletin boards for public notices.
These interesting stores are a good place to find announcements about up-coming meetings for groups such as the Christian Coalition, Concerned Women for America, Citizens for Excellence in Education, etc. Note the groups and individuals you find listed on these bulletin boards, and then enter that information in your databank. Some researchers visit conservative Christian churches in order to gather information. This is often an excellent, but overlooked source. Activist church foyers often display literature from local and national religious right organizations.
