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.
Information Privilege
Much of the most reliable and current information in a particular field is found behind a paywall where only persons associated with an educational institution or professional organization, or the monetary means to purchase journal subscriptions has access to this information. The inherent issues of academic publishing created a growing advocacy for the Open Access movement.
