An article or journal database is a searchable, online collection of information records, primarily journal articles, accessible through electronic means. These databases often include metadata like author, title, publication date, and abstract, and may also offer full-text access to the articles. Databases can be subject-specific (e.g., focused on medicine) or multidisciplinary (e.g., covering a wide range of academic fields). Each database indexes a unique set of journals for that discipline, however, there is often overlapping coverage in related databases. You may need to search more than one database to do a thorough search.
