----- Drago Kunej from Slovenia did the same for CD-Rs only and it was 
reported in:

Kunej, Drago: "Instability and Vulnerability of CD-R Carriers to Sunlight",
Proceedings of AES 20th Int. Conf. 'Archiving, Restoration, and New 
Methods of Recording', Eds. Z. Vajda, H. Pichler, Budapest 5-7 October 2001, 
pp. 18-25.

----- please note that I have finally corrected the subject line of this 
thread. This has something to do with my own retrieval - it is impossible to 
find the content of the thread if one searches for "hardy" which is what was 
meant, when "hearty" is what is logged. We would need a search engine built 
to retrieve "sounds like", but they are not in common use. In the early 1980s 
the Swedish company Skriptor (founded by the linguist Hans Karlgren) started 
offering collision searches for trademarks based on the sound of the 
trademark - a most relevant approach.

----- while I agree that XML is the most general approach to field definition 
and retrieval that I know about, it is what you put into the fields that 
counts, i.e. the way you think about your body of books, facts, records, 
fingerprints, etc. I can very seriously recommend a book that deals with how 
classification determines our thoughts:

Bowker, G.C. and Susan L. Star: "Sorting Things Out - Classification and Its 
Consequences", MIT Press, Cambridge MA 2000 (PB). 326pp and 51 pp. of notes, 
references, and index.
