The professional network acquired SlideShare for $118.75 million in May 2012.
Scribd said its premium subscription service offers more than 1 million ebooks, audiobooks, podcasts, sheet music and magazines, as well as over 100 million documents uploaded by its community, including study guides, business templates, academic papers, public court filings and other informational and educational resources.
Its acquisition of SlideShare will add over 40 million presentations to that ecosystem.
Scribd co-founder and CEO Trip Adler said in a statement, “Our acquisition of SlideShare is a major step toward creating the world’s largest digital library. Scribd has accumulated a unique collection of user-generated and professional content that we make available to our readers via personalized recommendations, and the addition of presentations from the SlideShare community advances our vision. It allows us to continue diversifying our offering while driving even more readers to the books, audiobooks, magazines and other professionally published works in our digital library.”
