Earlier this month, Elsevier had removed Rosen’s Emergency Medicine (9th ed.) from their ClinicalKey collection due to dosage and drug errors. While the text still remains inaccessible, Elsevier has released more information about specific errors, which you can read here.
According to Elsevier’s update, the text should be available during the week of February 5. In the mean time, the 8th edition of the text is available, which you can access here by clicking on the “Get It @ UML” tab and the hyperlinked Elsevier ClinicalKey Books title.
