The British Library currently has on display works in early English 
published about 600 years ago.  The medium was paper and a coloured 
deposit generally based on carbon (lamp-black) or ground minerals.  They 
last very well provided light is limited - which is the norm in closed 
books.  They tried transferring it to microfilm starting in 1938 - but 
have found that medium somewhat less reliable than the original.  Some 
lessons of history, it would seem, have yet to be learned.
