An imprint company called Strawberry Classics dedicated to producing novels such as Jane Austen and Charles Dickens in dyslexic-friendly font. The font is sort of heavy looking and is supposed to help people who have problems with tracking or experience letters jumbling or words slipping of the page when trying to read. Books can be bought on Amazon.
Speaking of dyslexic-friendly font, you might want to check out OpenDyslexia, which offers a free downloadable typeface.
Also if you find the above font useful, you can now select it as an option on Wikipedia's universal language selector when reading articles.
Another publishing house you might want to investigate for dyslexic children and adults is Barrington Stokes. They produce books that could be more accessible to dyslexics by using methods such as cream paper (to minimise glare), short chapters, clear spacing etc.
If anyone has any other suggestions of dyslexic-friendly literature I'd be interested to know- please leave suggestions in the comment box below.
