To All Learning Community Leaders, Faculty, Staff, and Students and Other Interested Parties:
We are delighted to share the contents of the 2019 Special Supplement on Learning Communities in Undergraduate Medical Education (UME), published by the Journal of Medical Education and Curricular Development.  The articles featured include research, educational case reports and perspectives pieces by faculty, students, and leaders affiliated with medical school learning communities, many of whom are affiliated in meaningful ways with the Learning Communities Institute.  These articles represent an important collection of contemporary ideas and practices in UME learning communities and we hope you will find them useful. Congratulations to all contributors for enriching this field with your scholarly efforts.
