From a KU Blog Post:
Knowledge Unlatched (KU) is pleased to announce that it has grown the impact of OA titles through its collections. In 2019, the number of total interactions (downloads and views) has grown by 50 percent to more than three million and on average 1,900 per title (a total of 1,559 unique titles). In 2018, the average equalled 1,800 per title (1,112 unique titles) and therefore also on a title level the impact is increasing slightly. These titles have been downloaded and viewed across more than 200 countries.
The title with the most interactions in 2019 was Ralph Schroeder’s Social Theory of the Internet (UCL Press), followed by William A. Pelz’s A People’s History of Modern Europe (Pluto Press) and Heike Paul’s The Myths That Made America (transcript). The academic institution with the most user interactions in 2019 was Johns Hopkins University, followed closely by Freie Universität Berlin.
The countries that continue to see the highest usage of OA books include the United States (one million interactions), the United Kingdom (220,000 interactions), Germany (150,000 interactions), France (100,000 interactions) and Canada (85,000 interactions).
