More recently, Goldberg and his colleagues have released the International Personality Item Pool which is an international "Collaboratory" which contains more than 3,000 short item stems summarizing the content of many personality inventories. At least 250 separate scales have been developed from the IPIP items, and at least some of the items have been translated into more than 35 languages. Validity data for these scales comes from a longitudinal sample of approximately 800 community volunteers in the cities of Eugene and Springfield in Oregon. These participants have taken the IPIP items as well as proprietary instruments measuring temperamental traits, occupational interests, and various activities. Goldberg, in his typically open spirit of collaborative science, provides the data from the Eugene-Springfield sample to interested researchers.
