Also being a blind Twainian, I might be able to point you in a few directions to find sources. As you know, the Library of Congress and other tape book libraries are very slim with their Twain offerings, but I've found it helpful to contact my local agencies that typically share a radio reading service with a taping service for the blind. If you're in a rural area, this might be difficult, but if you're near a decent sized city, volunteers are often available to put texts on tape for you. The process is often slow, but that comes with the territory. Many Twain sources are available on computer disc, but offhand I don't recall if CONSPIRACY numbers among them. Hopefully, Kevin Bochynski can give you more information when he gets back online (he's going to be involved in other matters a few days.) you might write him directly next week. He, or someone else on this list, might be able to send you files they have in their archives so you can work with them in your computer. Most text sources I've collected are the works themselves without all the valuable notes and scholarly apparatus that distinguish the UCAL editions. If you have a scanner, you'd be best off by getting the print editions to both have access to the supplementary materials and be more able to work with the text in your own writing work. This way, you can cut and paste material from the scanned text into your own work with the proper pagination, spellings, etc. from the authoritative texts. I've found this much easier than dealing with tapes. The same holds true for articles or books not yet available online.
