Marshall Breeding writes: “On May 17, research information company Clarivate announced it will acquire ProQuest for $5.3 billion—the largest transaction in the library sector to date. The acquisition means a change of ownership for ProQuest but will not substantially affect the products and services purchased by libraries since Clarivate’s products and services do not typically compete in the library market. As part of Clarivate, ProQuest and its technology businesses Ex Libris and Innovative Interfaces potentially gain access to resources that will strengthen its capacity in product development and support.”
