The following publications are subject-specific, but you don't need to be a professional in the field to understand them.
Trade magazines are published for people working in a specific industry, profession, or trade, and can also be useful for any researcher. Articles are often focused on current trends and practical issues. The writers are industry experts and other professionals and their credentials are usually listed. Trade publications can sometimes offer a specific "insider" perspective that cannot be found elsewhere, but you might need to look up some context if you aren't already familiar with the field.
