Literature of Lesbianism

I tried very hard to relate this article back to Pride and Prejudice, but I struggled to find a part of this article to draw from to take back to the characters of Jane Austen's novel. I did, however, manage to find some very interesting aspects of this article.
One of the main things that stuck with me throughout this article, was the idea of lesbian literature, and what are the qualifications of it. At first, it was determined that lesbian literature was written about lesbians, but then what about the women who were declared lesbians, or led homosexual lives?
"More damagingly, even as we labor (with greater or lesser unease) to pigeonhole individual women, we are confronted with the aggravating ambiguities of the term lesbian itself: its psychic and behavioral imprecision, its obscure to refer unequivocally, precisely at those moments when one wants most that it should." -page 5
I love this quote, because we, as people, and as readers, want to group things together, whether they be types of novels we read, authors we like to read, what those authors read or produce, and main themes we like to read about, we are forever trapped asking what types of novels one kind of author writes. This point was made specifically about women who may have led homosexual lives, but never related themselves in that way, nor would they relate their novels that they wrote in that way. These authors just wanted their novels to be something to read, something to be enjoyed, and something to be talked about, and not judged on what kind of content that they produced. This even goes as far as men who wrote about lesbians in their books. There is no way that readers could call men lesbian writers because men cannot lead lesbian lives. So this draws back the question of what defines a lesbian writer or novel, as well as any other types of novels or writers.
