The Social Register is a semi-annual publication in the United States that indexes the members of American high society. First published in the 1880s by newspaper columnist Louis Keller, it was later acquired by Malcolm Forbes. Since 2014, it has been owned by Christopher Wolf. It was historically a directory of "old money," well-connected families from the Northeastern United States. In recent years, membership has diversified both in the geography and ethnicity of those it lists. However, its importance as an arbiter of a family's social status remains.
