There are several databases that you can use to find articles. Remember that subject databases will only include journals that are within that particular subject area. In addition to the two main criminal justice databases, at the top of the list below, you will also find other databases useful. For instance, if you want the sociological perspective on crime, you could also use Sociological Abstracts, and for a psychological perspective, you could also use PsycInfo.
Some databases are more general. Academic Search Complete covers most academic subjects, while Science Direct is a good source for scientific articles.
Interested in the academic conversation of a topic, the history, or current science, then Scopus is for you! In Scopus you can easily find linked citations from an article. Web of Science also shows articles that have cited the primary article since it was published.
