These guys are a mixed blessing. The web site is slow-slow-slow, their search feature is none too helpful even if you happen to know exactly what you're looking for, their prices range from high to absurd and the descriptions of their products tend to be pretty terse or flat out non-existant, which is kind of lame for an organization aimed directly at blind customers. But besides that... They do have quite the collection of ideas and products, some of which you can find nowhere else. That they have made the effort to find, test and collect so much in one place justifies a little "value add" price hike.
These guys rock. I believe they are staffed by the blind. Prices are reasonable. Products tend to be down to earth and genuinely useful. Descriptions abound. They welcome questions. Ordering is online or by 800 number. And there's free "material for the blind" shipping. The only "trouble" I've had with them was that on one of my many orders one of my items was back ordered and they forgot to send it when they came back into stock. One quick phone call and that was solved nice and easy. I only wish they sold even more stuff.
As you might guess from the name bookshare.org shares books online to people with qualifying disabilities. in plain text, DAISY and BRF formats. Which books are available depends on what's sent to them by users and publisher and whatever they pick internally, apparently selected by popularity, awards, etc., so what they have is hit and miss. Membership is free for qualifying students and farily affordable (varying by country) for individuals. It's a nifty and useful if somewhat quirky resource.
