It stands to reason that a digital format copy be created to prevent permanent loss due to a variety of possible causes but, once a digital copy is created, it shouldn't cost that much to get the info on DVD or any other future format.
Wasn't there a recent creation of a "universal format" that won't be subject to change every few years?
There are several printed versions of the book available. I am using a Penquin Classics translation of the original in my genealogical hobby. It cost only $30 and is indexed as to place and surname. Unfortunately these names have changed over the last 1000 years and so the index is only half usable. But it is still fascinating reading although a bit boring as there is no plot, only lists of property, slaves, livestock, etc., etc. 1436 pages of very small print but does have an excellent glossary which is absolutely necessary.
