Hey again vhrsn... We keep bumping into each other on the boards.
I'm assuming you have either a braille feed from your PC or some voice-to-text capabilities, have you considered doing a google search for tarot texts available online. I know that Paul Case and A.E. Waite and several author's can be found posted at various sites.
That said, I HIGHLY recommend Joan Bunning's site at
www.learntarot.com. It IS illustrated but the text portions are exceptionally well-organized, thorough, and detailed. Comprehensive and yet something you could take in chunks as you have the time. She even offers the entire course as a downloadable file. She also published the curriculum as Learning the Tarot a few years back, but by using the website or the downloadable file you'd have the advantage of your PC's text capabilities. Is that at all helpful?
