Re: <-- cataloger in training
Ummmm good stuff, but not what I meant (and I did enough time in the school library in my day to know)
I was comparing the notion of a straightforward, widely known notion like "alphaetical order", which sorts without classification, and the Dewey Decimal system, which catalogues far more, for wont of a better term, ruthlessly, and is in no way obvious to a passing observer.
By stringently controlling the classification of the genres rather than a looser categorisation, the genre's have less freedom and wither away
