Bestcolleges.com has a new page devoted to College Resources for Students with Disabilities. It's a good basic guide to legal rights, campus life, and many resource links on disability and college life.
Its legal focus is Section 504 of the Rehab Act, but it also covers the ADA, IDEA, and the Assistive Technology Act. It gives general tips on finding a college and getting set up as a student.
There are sets of links to websites, apps, and software for Deaf/hard of hearing, visual impairments, physical impairments, autism, ADHD, learning disabilities, and dyslexia. More info: http://www.bestcolleges.com/resources/disabled-students/
