Final answer:
Trade publications are industry-specific resources that provide news, analysis, and information pertinent to a particular professional field.
Step-by-step explanation:
Trade publications are magazines and journals that cater to a specific industry or professional field rather than the general public. These publications often provide industry-specific news, analysis, and information that is valuable for professionals within that field. Unlike broader publications like Time or Vanity Fair, trade publications are designed to serve as a resource for industry insiders rather than offer general interest content. For example, Attorney at Law Magazine is designed for legal professionals, whereas Psychology Today straddles the line between popular readership and professional audiences but is not typically considered a trade publication. Trade magazines differ from peer-reviewed journals in that the latter are usually academic and require a rigorous review process by scholars in the field. Both types of publications, however, appear in print and electronic databases, which can be accessed through library websites, with scholarly sources often residing behind a paywall.
