Atypon®, a leading provider of software to the scientific and scholarly publishing industry, and American Psychiatric Publishing (APP), a division of American Psychiatric Association, have re-launched PsychiatryOnline on Atypon’s Literatum platform. PsychiatryOnline features DSM-5®— the most widely used psychiatric reference in the world — and The American Journal of Psychiatry as the cornerstones of a wealth of content that includes journals, textbooks, Psychiatric News, and a growing suite of DSM-5® products. With the significant increased flexibility conferred by Literatum, APP will now be able to continuously roll out upgrades and innovations that will enhance the value of the portal for subscribers.
