MZB edited 2 anthologies:
Sword and Sorceress, and the Darkover anthologies. The latter series ended with
Snows of Darkover in 1994, due to legal issues, I think.
Even though MZB died in 1999, her
Sword and Sorceress series has continued. It is currently edited by Elisabeth Waters and Ann Sharp. As of volume XX (2002), they say in the introduction that DAW publishers have decided to do volume XXI.
And I think that through editing these, and her
MZB's Fantasy Magazine, which ran from summer of 1988 to December 2000 (50 issues), she really opened up the fantasy market for a lot of young writers. For example, Mercedes Lackey, Jennifer Roberson, and Diana Paxson, among others, all sold their first stories to her.
Another author who often includes lesbian/gay characters in her stories is Canadian Tanya Huff. She again writes in the fantasy field, often with a touch of horror as well. One particular example is
Sing the Four Quarters, where a princess and the father of her unborn child try to rescue the princess's female lover. She is also currently working on the Summoning series:
Summon the Keeper,
The Second Summoning, and
Long Hot Summoning. The first and third are set in Kingston, Ontario, which I enjoy since I grew up there. Anyway, a character growing in importance as the series continues is lesbian, and has met someone.
And finally, there is also Gael Baudino. Although I haven't read her latest series, and I'm not sure when she last published, her book
Gossamer Axe, winner of the 1990 Lambda Literary Award for Lesbian SF&F, features a lesbian as the main character. As well, her Starlight and Dragonsword series include lesbian characters.
Maybe it's easier to include lesbians/gays in a fantasy world, and just have them accepted there, without all the baggage that comes with writing them set in the real world.
