The story
Medknow Publications was founded in 1997 in Mumbai, India by Devkumar Sahu. Sahu opted for the open access model of publishing services. In 2006, Medknow had 33 scientific technical and medical journals in its portfolio, at the time, one of the largest open access publishers of medical content in India.
Medknow was acquired by Wolters Kluwer in December 2011, extending its publishing partnerships in China, the Middle East, and other regions. As of August 2016, Medknow publishers over 370 medical society journals in over 40 specialties.
In 2013, John Bohannon submitted a fake paper to the Journal of Natural Pharmaceuticals, published by Medknow, as part of the Who's Afraid of Peer Review? sting investigating open-access publishing. The journal accepted the fake paper, and was subsequently closed by Wolters Kluwer, citing 'deep concerns'.
Many Medknow journal websites are now hijacked by spam websites rendering the journals inaccessible.
