When you’re writing a book or academic paper, giving credit is easy: You cite your sources with endnotes and a bibliography. It’s not so easy when you’re writing an piece of journalism. Conventions vary, from genre to genre and from publication to publication. My own practice, similar to that of many others, is to cite sources that provided specific pieces of information—and, when possible, to quote by name anybody who spent a lot of time helping me to understand an issue.
