The Korean Association of Medical Journal Editors (KAMJE) was founded in 1996. Among the 51 journals which participated in the founding of KAMJE, only 5 were listed in PubMed at the time, and none in Scientific Citation Index (SCI). In order to improve the quality of Korean medical journals, KAMJE established regular and systematic evaluation of medical journals, and has held academies for journal editors and education programs for manuscript editors. KAMJE has also focused on the database of Korean medical journals. KoreaMed, which provides access to articles published in Korean medical journals; KoMCI, which analyzes and provides citation data; and KoreaMed synapse, a digital archive and reference-linking platform. All of those are products of the efforts of KAMJE. By publishing "Good Publication Practice Guidelines for Medical Journals", KAMJE also has been focused on research and publication ethics. KAMJE has played an active part in establishing the Asia Pacific Association of Medical Journal Editors (APAME) and West Pacific Regional Index Medicus (WPRIM). Today, KAMJE, now composed of 188 journals covering medicine, nursing, dentistry, veterinary medicine, and nutrition, has 14 and 23 journals listed in PubMed and SCI, respectively. These achievements of KAMJE, attributable to the unrelenting efforts of Korean medical journal editors and editors, may be helpful in further improving the status of Korean medical journals.
