Pediatric rheumatology online journal is a refereed publication designed to meet the educational, reference, and communication needs of the international pediatric rheumatology community. The journal was begun in an effort to explore the educational potential of an online journal for a pediatric rheumatology community widely dispersed throughout the world. PROJ is attempting to serve as an excellent source of relevant information for this international community and as a way to improve how pediatric rheumatologic information is transferred and accessed.
