Why keep records?

I had a converation today with someone who could (would?) not understand why ArtLog is necessary. She maintains that Art is over documented as it is--that artists are generally paranoid,keep everything,blog, self promote and therefore, document all the time. Obviously, I do not agree. Artist may very well keep records but they tend to be for the purposes of stimulating the imagination or triggering responses and are arranged in a very personal kind of order that only makes sense to the artist themselves. I can remember arguing this concept with a writer at the centre who said he had his notebooks and wrote everything down.He had been at the Centre two/three years previously so I challenged him to tell me what he had been working on at that time. He came back somewhat chastened because while he had written about what interested him then, he had not actually written down exactly what he was working on. This, I think, is the point. Record making is one thing, but record keeping so that the records makes sense in a different time and place is a whole other thing. Its an old fashion notion otherwise known as history!
