Recently I was asked for a list of books for "an adult who is just beginning to explore whether or not they may be bi or lesbian". As someone who went through this many, many years ago and has written extensively on this topic, Faderman's book was one of the first that came to mind.
As individuals exploring our own sexuality - regardless of what that is - gaining historical context and perspective is a critical part of self-discovery. This is not the only book I'd recommend and it has a scholarly aspect which borders on clinical for a woman (or man or other) on the road to self-discovery.
I cannot count how many copies of this book I have purchased over the years, highlighting various passages which held out special meaning or purpose for me, and passed on to others. In the end, we all have our own paths and Ms. Faderman's book manages to cross most of them.
For those on a personal path, or those looking to understand the concerns and needs of a loved one trying to understand their place as a lesbian and bisexual in today's world, this is an excellent text for reading and gaining historical perspective. Bravo to Ms. Faderman for not 'updating' a historical text but letting her original research prevail.
