This article provides the first large-scale, longitudinal study examining publication rates by gender in philosophy journals. We find that from 1900 to 1990 the proportion of women authorships in philosophy increased, but it has plateaued since the 1990s. Top Philosophy journals publish the lowest proportion of women, and anonymous review does not increase the proportion publishing in these journals. Value Theory journals do not publish articles by women in proportion to their presence in the subdiscipline. Although the proportion of women authorships in philosophy has increased over time, measurable disparities persist.
