Oxford University Press (OUP) and Karger Publishers are pleased to confirm the completion of the acquisition of Karger by OUP. Announced in early November, the closing of the transaction means that Karger is now wholly owned by OUP and becomes part of the wider OUP organization.
Owned by the Karger family for four generations, Karger Publishers has a long history of high quality publishing in medical and health sciences. The acquisition brings together a shared commitment to quality and scholarly integrity and an opportunity to extend the reach and impact of Karger’s leading academic and research publishing in medicine and health sciences.
Nigel Portwood, CEO of Oxford University Press said: ‘‘I want to extend a very warm welcome to the Karger team, as well as their editors, authors, and customers. OUP is a department of the University of Oxford and one of the largest and oldest university press publishers in the world. This acquisition marks a significant moment in the history of our two organizations, underpinned by our joint publishing expertise, reputation for quality, and shared commitment to scholarly integrity.”
During the coming months, OUP and Karger plan to take some time to establish the best ways to work together. All current contacts remain the same and the 2026 sales renewal process continues as normal for both Karger and OUP subscriptions.
