Yearbook for Intermediate Sexual Types

The Yearbook for Intermediate Sexual Types (Jahrbuch für sexuelle Zwischenstufen) was an annual publication of the Scientific-Humanitarian Committee (Wissenschaftlich-humanitäres Komitee, WhK), an early LGBT rights organization founded by German sexologist Magnus Hirschfeld in 1897. The periodical featured articles on scientific, literary, and political topics related to sexual and gender minorities. It was published regularly from 1899 to 1923 (sometimes quarterly) and more sporadically until 1933.
