Sadly, there isn't much because AS was only added to the DSM 11 years ago and most diagnosis have only started happening within the last few years. As with Autism, AS is usually diagnoised in childhood because it is catagorized as a developmental disorder, but this isn't to say one out grows AS/Autism, so adult diagnosis do happen.
There won't be much information available on adult AS for another 10 years, but in the mean time you can start reading about Non-verbal Learning Disability (because it is very, very simaliar to AS, and in fact AS may be an extreme form of NVLD instead of Autism, but that is another post in it self) at this URL
http://www.nldline.com/as_vs_nld.htm and read anything you can find about adult High Functioning Autism.
As you will discover in reading about NVLD and how it relates/compares to AS, there are significant differences between Autism and Asperger's Syndrome, most noteworthy being that the Neuropsychological profiles of Autism and AS are the exact opposite of each other. In fact the profiles of AS and NVLD are almost indistinguishable, but regardless of this the symptoms of AS present themselves in such a way that they appear to be much like Autism, and as such, it has been catagorized as a PDD.
