Paywall
A paywall is a method of restricting access to content via a paid subscription. Beginning in the mid-2010s, newspapers started implementing paywalls on their websites as a way to increase revenue after years of decline in paid print readership and advertising revenue. In academics, research papers are often subject to a paywall and are available via academic libraries that subscribe.
Legal research in the United States
Many law reviews, other legal journals and magazines, and legal newspapers place content on the web. Not all law journals provide their text on the web, and some content may be placed behind a paywall.
