- KPOV's citizen journalism handbook for radio (pdf)
- FAIR's investigative journalism manual. (This FAIR being the Forum for African Investigative Journalists , not the anti-immigration group.)
- Story-Based Inquiry - step by step investigative journalism, "treats investigative journalism as an integrated process focused on producing an original story." (h/t HelpMeInvestigate's 5 ways to simplify an investigation; added 2011-08-08)
Of the 3, the last seemed most worthwhile; but all are helpful.
