A multidisciplinary or general database is one which covers a wide range of topics across multiple academic disciplines. You may want to use a multidisciplinary database if your topic is cross-disciplinary, or if you are not yet sure of the subject area into which your topic falls.
Web of Science: Large multidisciplinary database offering citation linking and citation counts.
Scopus: Large multidisciplinary science and social sciences database that is capable of backward and forward citation linking and includes citation counts.
A subject-specific database focuses on a single discipline (e.g., Agriculture) or a group of related disciplines (e.g., Economics, Finance, & Business) and usually provide comprehensive coverage of that specific field. Using a subject-specific database is ideal if you know a particular subject area is appropriate for your search topic.
