What are the key differences between a trade journal and a scholarly journal in terms of their content, audience, and purpose?

Trade journals are publications that focus on industry-specific news, trends, and practical information for professionals in a particular field. They are aimed at professionals within that industry and often include advertisements and product reviews. Scholarly journals, on the other hand, contain academic research and analysis, aimed at scholars and researchers in a specific academic discipline. Their purpose is to contribute new knowledge to the field through peer-reviewed articles and research studies.
