E-journals, or electronic journals, are digital versions of academic or professional publications that provide access to research articles, reviews, and other scholarly content. They are typically available online, allowing users to read, download, and share articles easily. E-journals cover a wide range of subjects, making them valuable resources for students, researchers, and professionals. Many e-journals are part of larger databases, such as JSTOR or PubMed, which aggregate content from various publishers. Subscriptions may be required for full access, but many institutions, like universities, provide their members with free access to these resources.
