ResearchGate

ResearchGate connects scientists and academics for sharing papers, data, and Q&A. It offers free full-text access to many publications plus citation metrics. Compared with Scribd, it lacks consumer topics, presentations, and a consumer mobile reading app. Pricing is free for core use with optional premium features for authors. Researchers needing specialized scientific literature choose ResearchGate, whereas Scribd’s subscription better serves general knowledge seekers who also want business and lifestyle documents.
