It's a sad fact of Internet research that useful sites with good information can up and disappear without warning. Sometimes it's just a matter of an organization changing its Web address; other times, service-provider issues put pages out of contact temporarily or permanently, or site writers simply move on.
And sometimes, as with the site for Sensory Integration International (SII), it's more complicated than that.
I've frequently recommended the SII site to parents new to a diagnosis of sensory integration, for its excellent FAQ and its directory of occupational therapists qualified to do sensory-integration therapy. Sensory-integration pioneer A. Jean Ayres, author of Sensory Integration and the Child, was a founder of SII, and that made it an authoritative resource for information on the subject.
But you won't find information on the SII site anymore. You won't find the site anymore, either. It's been taken down as part of a business dispute over the way the foundation managed its finances, mismanaged refunds due for cancelled workshops, and misused the name of Ayres, who died in 1988.
The magazine Advance for Occupational Therapy Practitioners has a lot of the gory details, including an article from last summer about the preliminary injunction that effectively shut SII down. At that time, the website was still up, but it has since disappeared, and a phone call to SII's Torrance, California offices got a disconnected message.
The case against SII goes to trial in July 2008, and perhaps the organization will rise from the ashes. In the meantime, though, it's time to look for new online resources for sensory integration and sensory processing. Here are some that I recommend. Have you found any good ones to share?
