The Siouan Archives were prepared in ...-..., before the Center existed, in a project headed by David Rood and Allan Taylor.  They were intended at the time to represent a computerized archive of all available primary materials on the Siouan languages.  The intention was to create computer readable versions of all these documents.  Siouan is a small language family and sadly underdocumented, but even so David and Allan were perhaps a bit ambitious.  A few things didn't get computer formatted and proof reading is still in progress, though most of the unkeyed references are available in the Library.  What was computer archived was put into a format conceived for a Control Data Corporation 6000 series system, c. 197?.  This system had a 64 glyph character system, which called for some ingenuity in encoding.  Over the years some of this material has been updated and we even make parts of it available on the Web.  We are presently engaged in a project to make the whole of the Archives available in a contemporary format.
