POPLINE has been a valuable resource to the population, family planning, and reproductive health community for over 40 years. The collection of more than 400,000 records has provided students and researchers worldwide with access to journal articles, reports, books, unpublished resources, and full-text documents (to users in low- and middle-income countries). POPLINE is managed by the Knowledge for Health (K4Health) Project, which ends on September 10, 2019. The POPLINE website will retire on September 1. Since POPLINE’s inception in 1973, many free resources have become available and offer alternative access to journal articles. These resources collectively meet the majority of POPLINE user requests.
