harrisons principles of internal medicineA printer’s page-proof of the 2nd edition of Principles of Internal Medicine with corrections by editor-in-chief Tinsley R. Harrison, MD. Harrison completed his work on the 2nd edition while on the faculty of the UAB medical school. This page-proof is part of the Tinsley R. Harrison Papers (Manuscript Collection 3) which are housed in the UAB Libraries as part of the UAB Archives.

In honor of the textbook’s founding editor, Tinsley R. Harrison, MD, the UAB Archives and the Lister Hill Library at University Hospital have mounted an informational display to highlight Dr. Harrison’s connection to the UAB medical school and his work as editor of the original Principles of Internal Medicine. Harrison served as editor-in-chief through the first five editions. The 6th edition of 1970 was the first to appear as Harrison’s Principles of Internal Medicine, having been officially renamed in honor of the book’s founding editor following his retirement.

Harrison’s Principles of Internal Medicine remains one of the “definitive clinical references” for any physician or physician-in-training and remains one of the best-selling internal medical texts in the world. In 2012 JAMA stated that the textbook was “arguably the most recognized book in all of medicine.”

The Harrison informational display is located in Room P235 in the West Pavilion of University Hospital. UAB faculty, staff, and students are welcome in the hospital library during business hours, normally 7:30 am until 4:30 pm Monday through Friday (with slight variations depending on staff availability).
