The Spanish Pediatric Association (Asociación Española de Pediatría, AEP) has as one of its main objectives the dissemination of rigorous and up-to-date scientific information on the various areas of pediatrics. Annals of Pediatrics is an open access journal that serves as the Association's Scientific Expression Organ and constitutes the vehicle through which members communicate. Annals of Pediatrics publishes, in English and Spanish, original research papers on pediatrics, as well as review articles prepared by experts in each specialty, and guidelines or positioning documents prepared by the different Societies/Specialized Sections integrated into the Spanish Pediatric Association. The journal, a reference for Spanish-speaking pediatrics, is indexed in the most important international databases: Index Medicus/Medline IBECS, IME, SCOPUS, Science Citation Index Expanded, Journal Citations Report, Embase/Excerpta Medica, Directory of Open Access Journals (DOAJ).
