The Jefferson Digital Commons Reaches 1 Million Downloads

The Jefferson Digital Commons is the free digital archive for: articles published by Jefferson authors, Jefferson-sponsored journals, and historical materials from the University Archives and Special Collections. Starting in 2006, the goal of the Commons was to enhance the visibility of Jefferson scholarship and to promote Jefferson authors.

Faculty testimonials

“I appreciate very much the widespread publicity that I have gotten through the Jefferson Digital Commons.  I am astounded that there have been over 19,000 requests for my article!  I greatly appreciate the monthly email alerts with download counts.  The library staff make it easy to deposit materials…(especially in terms of copyright review).  This has provided a great venue for sharing my work with a global audience” –James S. Studdiford, MD, FACP; Professor, Department of Family and Community Medicine, Thomas Jefferson University

“Since [my] article was published in the JDC, I have received emails from around the world thanking me for publishing the article and telling me how it has helped their students or staff.  Publishing in the JDC is also good for authors that want their works to be seen by individuals outside of those with subscriptions to specific journals.  Widespread dissemination of knowledge helps promote better education in the health professions and should not be limited to only certain individuals.” –Traci B. Fox, MS, RDMS, RVT; Assistant Professor, Department of Radiologic Sciences, Thomas Jefferson University

“As a researcher in sport injuries, I receive numerous national and international inquiries weekly from team athletic trainers, sports med clinicians, and even athletes themselves requesting manuscripts, digital art and tables published in subspecialty journals or textbooks.  The JDC provides a portal through which we can share our research and presentations to an audience who might not otherwise have access.  This is an incredible powerful tool for spreading the word on what we do here at Thomas Jefferson University.” –Adam Zoga MD; Assistant Professor, Department of Radiology, Thomas Jefferson University

“JDC couldn’t be easier to use! Scott Library staff did all the work to verify copyright permissions from different journals. … the Author Dashboard gives me a snapshot of the search engines and terms people used to find my work and which institutions downloaded files over the past month or cumulatively. I’ve been impressed by the global reach that JDC has made possible and over the past 3 ½ years I’ve received several email messages from readers thanking me for making the articles available to them.” –Mary Muhlenhaupt, OTD, OTR/L, FAOTA, Assistant Professor, Jefferson School of Health Professions, Department of Occupational Therapy, Thomas Jefferson University
