The open access effect in social media exposure of scholarly articles: A matched-pair analysis
作者：
Highlights：
• The paper examines OA effect when a journal provides two types of link to the same subscription article: OA and paid content.
• OA links perform better than paid content links. When not indicating the OA status of a link, the performance drops greatly.
• OA benefits all countries, but its positive impact is slightly greater for developed countries.
• Combining social media dissemination with OA appears to enhance the reach of scientific information.
