Trade Journals (also sometimes called "Industry Publications" or "Professional Magazines/Newsletters" are publications that connect people in a particular professional field with information specifically useful for that profession. For example, the magazine Aviation Week & Space Technology publishes news, summaries of recent research, and best practice guidelines for aviation, aerospace, and defense professionals.
Trade articles are good to keep people in a particular field of work (veterinarians, police officers, hotel managers, advertisers...etc.) up-to-date on trends in their line of work. Articles often summarize and analyze findings from scholarly research.
