Here from Proud Parenting GLBT Youth, comes a history of literature with lesbian themes for young adults. Publishers of the earliest title mentioned, "Spring Fire" (circa 1951) told author M.E. Kerr that the book could not have a happy ending otherwise the postal service would not allow it to be sent through the mail.
A recent title is "Keeping You a Secret" by Julie Anne Peters, who commented â€œA wide disparity of attitudes exists at the school library level. Iâ€™ve had a librarian tell me, â€˜Iâ€™d never put your book in my library [a Colorado high school library] because no kid would be caught dead carrying a book like that around.â€™" But, she maintains, "there are growing numbers of teachers and librarians who are vocal advocates for serving the needs of LGBTQI youth, and their passion is contagious."
For the acronym-challenged, here's a definition of LGBTQI from this website; it means "a common abbreviation for lesbian, gay, bisexual, transgender, queer and intersexed community."
