Joy of Autism has been a great resource. It's by a mother in Canada. She's not posting as often any more, but the archives are golden.
Autistics.org Library has a bunch of essays by autistic people about things most of us don't have to think about. The most telling things for me are the ones about playing the role of brave disabled person for the benefit of others, knowing that it helps them set themselves above you and not feel threatened by you. There are also essays on being institutionalized, abuse, activism, daily living, effects of drug use, etc. Very honest.
Getting the Truth Out is a very in your face photo-essay. It's a long emotional slog, so clear out a good hour. It lulls you into thinking it's one thing and then becomes something completely different.
Born on a Blue Day is an autobiography by a dude that not only has Aspberger's but also synesthesia. He sees numbers as shapes and can do ridiculous math in his head. It isn't really savant-focussed. It's just about this dude's life and struggles and joys. I kept expecting something horrible to happen in the story because something horrible always happens to autistic people in stories, but this book is all about some happy endings.
Animals in Translation is a book about animal behavior by animal behavior specialist Temple Grandin. She is autistic. While this book is more about how animals think than how autistic people think, she says that in her case the thinking appears the same. She's written other books specifically about autism, but I haven't read them yet. This one's fascinating, and I do not like animals unless they drink alcohol and drive Escalades
Autistic Planet,
Different Like Me, and
I am Utterly Unique are children's books. They have a wonderfully positive point of view and are a great way to share just a little bit of information about autism to children and adults who might be curious. Because they're children's books, they're not intimidating to people who just want to learn a little. And because they're not gloom and doom, people will actually flip through and learn what they have to offer. It's pretty neat.
