The Journals of Gerontology are the first scientific journals on aging published in the United States. The publication is separated into four separate peer-reviewed scientific journals, each with its own editor, and published in two series. The Journal of Gerontology: Biological Sciences and the Journal of Gerontology: Medical Sciences are housed within The Journals of Gerontology, Series A; the Journal of Gerontology: Psychological Sciences and the Journal of Gerontology: Social Sciences are housed within The Journals of Gerontology, Series B. The journals are published by Oxford University Press on behalf of The Gerontological Society of America.
