Where did Virginia Woolfe get the title for her book, A Room of One's
Own....was it related to an Emily Dickinson poem and if so which one?

I don't think there's much evidence that VF read ED's poems; and it's
quite possible that, if she did, she didn't like them. "A Room of Ones
Own" has that title because that's what VF thought that women writers
needed - together with an income of 500 pounds - if they were going to
match the best male writers.

Sorry for the mental abberation above. VF should of course be VW (Virginia Woolf),

Perhaps, but many sites for Emily Dickinson come up with this with a
similar quotation  - such as this one:
Barnes & Noble.com - Poems of Emily Dickinson - Emily Dickinson ...
ABOUT THE BOOK. Poems of Emily Dickinson ... Only poems, written quietly in a
room of her own, often hand-stitched in small volumes, then hidden in a desk ...

This seems to be a quotation by someone else about ED's writing in
seclusion, perhaps in the introduction to a early published volume of
her works.

Maybe someone can source the line.
