I believe that it is illuminating to look at some of the anthologies devoted to women and become acquainted with their work. Then I, at any rate, would be surprised if the reader, male or female, did not find some about whom he/she asks "Why have I never heard of THIS poet before." It may just be possible that some readers have figured out an answer but actually do not understand the problem.
I am small fry and I cannot complain personally about the responses I have had from editors over the years. However, that doesn't mean that I am not aware of the problem of women's visibility in a larger perspective.
I have in front of me a number of anthologies. Here are some titles:
The Faber Book of 20th Century Women's Poetry (ed. Fleur Adcock),
Sixty Women Poets (ed. Linda France),
Modern Women Poets (companion anthology to)
Consorting with Angels (essays on women poets) (editor/author of both Deryn Rees-Jones),
100 Great Poems by Women (ed. Carolyn Kizer),
The World Split Open: Four Centuries of Women Poets in England and America, 1552-1950 (ed. Louise Bernikow, preface by Muriel Rukeyser). I have another I can't think of the title edited by Carol Rumens but can't find it. I have still more, but cut to the chase.
Here is a suggested experiment. Go to a bookstore and open an anthology of women poets. Look at the "Contents" page and consider how many you have never heard of before. Buy it and take it home and read it .
You won't like everything there, who likes "everything" in any anthology, but a fair-minded reader will likely find as many gems as in a "regular" anthology. (The gals will find more, perhaps.)
Remember a few weeks ago when U. A. Fanthrope died (it was Duncan Gilles who brought her death to our attention) and I posted her "Not My Best Side". And Michael Cantor burst out, "That's wonderful" or some such similar expression for which I gave him a virtual hug and many fond thoughts for his spontaneous compliment.
I think next to all of our male members here are fair-minded friends and I am not bashing them. Or anyone else, I'd best add. But facts are facts, and there a lot of fine women writers out there whom many have never heard of because they do not make into the mixed-gender anthologies.
Just saying.
