Don Lindberg's Outreach Legacy at the National Library of Medicine.

Friends and colleagues of Donald A.B. Lindberg M.D. came together to give tribute to his extraordinary contributions during his tenure (1984-2015) as Director of the U.S. National Library of Medicine (NLM). Dr. Lindberg died in 2019. The book, Transforming biomedical informatics and health information access: Don Lindberg and the U.S. National Library of Medicine. includes four sections. The ten edited chapters in section three (the Outreach section) are briefly summarized in this overview. As Associate Director for Health Information Programs Development, Elliot R. Siegel Ph.D. coordinated NLM's outreach programming under Dr. Lindberg's leadership from its inception in 1989 to his own retirement in 2010. Dr. Lindberg's legacy at NLM is one of new possibilities imagined, significant changes made in the mission and ethos of a venerable institution, and numerous successes achieved in a variety of settings and contexts. Like so much else Dr. Lindberg accomplished, these Outreach programs that profoundly changed the character of NLM would likely not have occurred without him. He made a difference.
