Scholarly journals are the primary means by which college professors, especially scientists, communicate and share their research findings. Journals are physically formatted like magazines but differ in important ways. They are peer-reviewed, with content decided by experts in the field rather than advertisers. Articles provide in-depth analyses for specialized academic audiences. Readers access journals digitally through university libraries or databases. Authors are typically not paid, contributing for prestige and to disseminate their work, while journals rely on subscriptions not advertising for funding.
