Unless you are in a state with gifted laws you are fighting a very long uphill battle in most cases. My DD9 has asperger's and is gifted as well. We have an IEP that addresses her speech therapy as related to the aspergers and her creative writing in ELA, she uses a keyboard. We have some other accomodations and because we are in a state without gifted laws we wrote a partial day into her IEP. So she attends public for ELA and speech only and homeschools everything else. The public school said they basically can't do anything for her in the other subjects because the grade level. Her reading level is much, much higher but we are holding her at only one grade level above, hoping for two this year, to allow the school to address her writing and pragmatic language needs, which are closer to grade level.
As far as the library goes, many AS kids don't like fiction and are often reading fiction much below their reading level with non-fiction material. My DD is just now beginning to read fiction on grade level.
