This series consists of 367 zines dating from 1973 to 1995, likely collected by the donor from 1992 to 1995. The collection primarily includes personal zines by women (though some are by men) that focus on the riot grrrl scene, feminism, punk music, and progressive political causes. Many of the zines include correspondence from the authors.

Zines and zine-adjacent self-published items collected or sent to Halliday.

The zines have been divided into sub-series based on editorship by women or men; zines are filed under women if they are co-edited and at least one editor is a woman. Within each sub-series, zines are alphabetized by title. Each folder contains an individual title with a range of issues included if known.
