Ser. 9 The Halcyon, 1887-

Swarthmore College's yearbook, "The Halcyon," first appeared in 1883. It covered the 1882-1883 school year and was printed by the Junior Class (the class of 1884). The following year, the college's annual was an issue of "The Eunomian," covering the 1883-1884 school year with much the same content as "The Halcyon." For the 1884-1885 school year, "The Halcyon" was published again, and an issue of "The Halcyon" was printed for nearly every year up until the 2010s. No "Halcyon" was published in 1965. It appears one "Halcyon" was published to cover the 1975-1976 and 1976-1977 school years. It is unclear whether any "Halcyon" was published in 1993, 2011, or 2016. No "Halcyon" was produced in 2017 or 2018.

"The Halcyon" was originally published by the Junior Class, and the covers were printed accordingly with the Junior Class year. For example, the "1891 Halcyon," with a cover labeled 1891, was published by the class of 1891 but documents the 1889-1890 school year and was actually printed in 1890. This system continued into the 1950s. The "1955 Halcyon," with a cover labeled 1955, was published by the class of 1955 but documents the 1953-1954 school year and was actually printed in 1954. In 1955, "The Halcyon" was reorganized, invitings students from all class years to join the editorial staff. The "1956 Halcyon," with a cover labeled 1956, does in fact document the 1955-1956 school year. For all subsequent yearbooks, the cover date reflects the publication year.
