I'm not sure if it's okay to post it here, maybe /o/WomensHistory is a better fit... but I hope it is. If not, please let me know and I'd post it there or in any other appropriate circle.

I think this is a real treasures, and it's just really cool and interesting to browse through these publications and see what feminists thought back then, what they were dealing with, what have changed, what didn't...

There is also a collection of LGBT, which might also be of interest. I think all of the publications of and about lesbians are already in the Feminist collection, though, but maybe you'd find it interesting all the same. I don't know if trans has any representation here, it seems to be mostly or entirely for and about gay people.

This is the description of the collection by JSTOR:

The LGBT collection contains 25 publications that chronicle the birth of the Gay and Lesbian movements in the United States. The gay liberation movement of the 1970s saw political action explode through the National Gay and Lesbian Task Force, the Human Rights Campaign, the election of openly gay and lesbian representatives, and the first march on Washington for gay rights in 1979. Frustrated with the male leadership of most gay liberation groups and influenced by the feminist movement of the 1970s, lesbians formed their own collectives, music festivals, newspapers, bookstores, and publishing houses and called for lesbian rights in mainstream feminist groups like the National Organization for Women (NOW).

Anyway, I hope you find it interesting!
